I went like in 1.75x speed and that's fine as well. Great video, although I'm still confused about state management, tons of unnecessary re-renders of the whole app and much more. We are not quite there yet. But I have to admit this is easier to understand for newbies
I wish I had a video like this for every programming language, it's so in-depth, I really like learning the underlying philosophy of a language rather than just the basic functionality.
Good news, except for the hoisting all the rest works pretty much the same in all languages. Operators exist just you have static typing. The scope and outter scope is a general concept in all languages. This is basically a course in computer science
Do you know this nice feeling when you finally understand something that has been bugging you for a while? That bliss of comprehension? I had this several times during this video! Thank you, Tony.
Most of the technical videos here on youtube are presented by people with an adequate grasp of their subject matter - I believe. But this guy actually knows how to teach. It is unlikely that any person with a basic understanding of Javascript can watch this video without understanding the material. Keep 'em coming, Tony.
Tony Alicea Sir how to download your video. I'm 2014 passout sir. I'm interested in front end development. Now I'm taking course on this, but I'm getting confused. Please help me sir. If you can please send me html,css,javascript videos to my mail sir.
At 2:09:45 you, correctly, say "the same associativity". However, 9 seconds later, your mouse is hovering of the same 'order of preference' despite your repetition of "associativity". At 2:11:23 you remove all doubt about which column is, in fact, declaring associativity. I concur with David that this is an excellent course and I will be continuing to follow you. Please put up some application building blocks type courses that show how to manage typical functions of most high traffic websites. Much thanks for your time and abilities.
I bought this course years ago and I still use it to refresh my basic concepts. When I have job interviews and they ask about JS fundamentals, my thought process goes right to this course! It is clear, concise and delivered in a slower manner so you can absorb everything he teaches. I love this course! I recommend this course to everyone I know who is stuck on JS. I think Tony Alicea is brilliant!
26 minutes in and already I am ready to buy every single course you make . What an inspirational teacher you are. I feel like Neo when he unplugged from the matrix and said “I know Jujitsu”
Just in the first 15 minutes i was blown away by how well thought out and put together this course is, i will most likely be paying for the rest. Keep up the hard work, youre an excellent teacher.
The absolute best tutorial ever on JavaScript. The author stays true to his vision throughout the entire course. I am pretty amazed how well they have been put up. Why would one give 3 hrs course for free ? Because, the author believes in his work and it has paid off, as I myself am going to buy the entire lesson even though the price is more than what I can afford for the country I live in. BEWARE: The quality of this material is so good that you might even think twice to refer other tutorials anymore. Tony Alicea You are the man.
I watched whole 12h course 3 times (I watch it every year since bought it), probably the best javascript course I have ever seen. I have 4 years experience but still learned new interesting things. During job interview I knew every answer about javascript (probably better than interviewer), thanks to this course. Even if it's old ES5, it's still worth buying because new javascript like ES6, ES7... is usually transpiled to old ES5.
Adding a comment as this is great content and still valid 7 years later. The best part is that way the information is delivered feels like a college lecture. This has been very helpful!
I've gone through a bunch of udemy courses, and I consider this one the most essential. These first 3.5 hours are by no means the most interesting or informative (believe it or not)

Amazing clarity. A teaching philosophy and presentation that is totally spot on. Most of us dive in to things to get the job done. I've been using JavaScript as required for 15 years but sometimes going back to first principles, when guided by a really good teacher as you are, can really pay off. The part where your first real JavaScript program is a blank screen is absolute genius - that might sound strange if you haven't seen it. Thank you.
I am a trainer and was looking at ways to find my lost class! You did it! With concise explanation every bit of the code is simple to understand and even the scared students started having smiles on their faces! This is what varsity lecturers should be doing! I am going to purchase the course! Dude thanks all the way from South Africa!
This is excellent! The information here is already changing the way I code. I am not guessing anymore. I am understanding and confident about how and WHY my code works. I have purchased the full course and am continuing to grow a rich understanding of the hows and whys of JavaScript. Rest assured the rest of the course continues to provide deep and valuable tools. Thank you Tony Alicea for providing the first few hours free as I am usually a cheap skate and would not have considered paying without confidence that this course does answer my questions and makes me a better programmer.
Amazing, Im in the middle of the video, and I finally understand a lot of the things that I couldn't properly with other courses and books (like javascript the best parts, and Eloquent javascript). I now bought the full course (first time buying on Udemy or any of the online courses). Thanks for the discounted price, I couldn't afford it any other way (I'm from Chile and the change between CLP to US is brutal now).
+Noah Namey Yeah this is my second time watching just the first 40 minutes, still trying to understand the lexical scope. Any resource that has the six year old version of explaining lexical scope? Would be a big help to me.

This was amazing! I understood everything and Tony is awesome and speaks in a way i don't get confused. Definitely will buy this course as soon as ill have money. Thank you, sir! You are the best!
Just finished the first three hours and I'm blown away by how well the material is presented. I purchased the full course on udemy for $19 and ended up getting the Angular course for $19 as well. I feel bad only paying that amount.. it's a steal. Keep up the great work Tony! I will definitely be back for more. I'd love to see a React-JS course offered.
Across many years, this is my single favorite video course, the one I remember most and enjoyed most. I'm going through the entire course a second time (udemy), and am still learning a lot. This Weird Parts course is unique and very special...you don't spend the first half day learning how to add and subtract. You dive right in. Anything you learn is immediately usable across Javascript, its all conceptual. Broad-based.
The world needs your tutelage. I honestly came here on a whim. Started watching your (free) video & just couldn't stop watching. You have really thought about this video. It's just beautiful. You really know your stuff too. You teach things that really require knowing. Your video is gorgeous - pin sharp & I love the way you really zoom into the important code; I've seen many videos where I can't even read the stuff on the screen. Your presentation is impeccable. I've watched an unhealthy number of videos on all sorts of stuff & this is the best of the best. Needless to say I purchased the rest of the course. Please keep it up!
@@succeeder3044 I'm about 60% of the way through. Initially, I didn't find javascript easy to debug because I didn't know what was going on under the hood but this course has helped tremendously with that. Just started the chapter on Functional Programming. I set the speed on 1.25 or 1.5 and then go over any parts I don't quite get the first time.
I have to say when i forget anything related to JS, I always get back to this course it's really GOLD, Thanks Tony you really did a great job creating this course.
The first 3.5 hours have been so good, I just followed the link in the video description to Udemy for the full lecture list, and spotted exactly more of what I need explained -- I'm new to programming and JS and this is exactly what I need to better understand others' more advanced code. Thank you!
You really hit the nail on the head at @11:00 I was one of those that were introduced to front end dev with all the frameworks and Jquery already in place. It was really hard for me to understand what's what.
This video is perfect. I'm a hobby web developer of 5 years and I'm about to attend a bootcamp and try to change my career permanently. This video is giving me a deeper understanding of JavaScript then I've ever had by far. Thank you so much!
In the world of programming someone finally takes the time to produce a help video that actually helps and doesn't just copy and paste the getting started page of into video format. Bravo! This is well thought out and well produced and has a solid mission.. Understand how it works and you won't have to memorize every usage case. The only criticism I can think of, and its not really a criticism, it the tempo of the narration.Its a bit slow but it does allow the consumer to think along the way. Great content. Great font size. Great editor colors. Great volume. Just a pleasure to watch.
As i have ADHD and autism i still sat through a 3 hour video. That's probably because i love to code. Love to learn. This is something i have a passion for. It stands out. Thank you for this. This video was chosen out of many other tutorials that i could've chosen. I chose this one. Thankssss
Tony, I have really been struggling with the JavaScript. This video seemed to pull together everything I was struggling with and explain it in a new way that I can understand. Can’t wait to take the rest of the course. You have rejuvenated my excitement for wanting to learn JavaScript. Thank you Sir!!!!!
This is the BEST JAVASCRIPT TUTORIAL!!!! I was learning on freecodecamp, doing the exercises without understanding what the heck I'm doing. Tony explains each concept in detail and repeats the messages so that you can remember! Thank you thank you!!
this was by far the greatest Javascript tutorial I've ever seen. God bless the algorithm as well as this man for such a well explained and incredibly competent explanation of Javascript.
Long term suggestion: If you know anything else with even half the depth that you teach JS and Angular, you should do videos on those too - Linux shell, Databases - MySQL, NoSQL, Server Side languages - J2EE / Python / PHP. You know how to teach well. That skill / gift crosses technology boundaries.
I'm a Javascript developer for the past year and half. I feel fluent writing and reading it. Just bought this course because it really grounds my intuitive understanding of this language, and extends my theoretical knowledge about it, eventually making me a better & complete developer.
I love this style of teaching. You have explained and ingrained fundamental JS concepts better than any other course. I've been struggling fully comprehending JS for months and this was just *BOOM* what I've been missing. Bought the Udemy course just now and am looking forward to finishing it. Thank you!
Bopy Tony you ain't kidding when you say that this is a very deep look inside Javascript! I have seen other JS tutorials but you REALLY probe deep into it.
Purchased your course today!! Once you started describing the objects, I new that this course was a great investment. Thank you very much for your course.
You need to have the right expectations for this course. It's an excellent collection of videos for you if you basically haven't spent any time with javascript at all yet, so you want to learn the fundaments as well as understand the weird parts. Tony takes the time to explain every small maybe 'obvious' fundamental multiple times, which is great if you're a complete novice to javascript. If you already have javascript knowledge and are excited about the weird parts and depths of this great language, the slow pace of the videos and multiple explanations of basic concepts as well as constant demoing in the console of stuff that you already know how it will look like, can be a bit tiring and forces you to constantly hit the skip 5 seconds button or set the playback speed to 1.25 or more. Like I said, just have the right expectations. This course is not only about the exciting weird parts - it's about those AND about all the basic fundamentals of the language, well explained to a high level of detail so that a person completely new to the language can understand it.
I can affirm for sure, this 3.5 hours make a lot more sense than many others pay courses for js fundamentals. I'm very impressed with the in depth explanation and professional approach. Thank you very very much for this truly hard and unique work.
sir .. how about this function b() { console.log(x) } function a() { b() } a() var x = 5 its return undifined .. if the execution stop when a( ) is invoked then var x should be not exist in memory and its return eror .. what i miss here in this course ??
This 3 hour course is so amazing! Understanding the global lexical environment and execution context is so important in regards to where things sit and how to understand how JavaScript works under the hood. I wish that this teacher had a million other videos!! I should have paid Tony the amount of money it took me to earn my degree in computer science. In three hours i understand more this topic than I did in four years.
Tony, a) I'm just about to buy your course and b) how lovely it would be to see what you make of ES6, and teach it to us. You are an outstanding teacher, and as such, a credit to the profession and to the species. No joke. Thanks for this work of art.
after watching this for the third time in a row, i decided to get the course. i like the emphasis on the philosophy of javascript in order to better understand javascript as a whole. nicely done sir!
As T. Reno says below, at 3 minutes in you said "Don't imitate. Understand." When I heard that I wanted to give my wall a hug (video projected). Tony, I thank you from the bottom of my heart. THIS is the video I've been looking for... I'm a bit more than half way through and loving it. I used to write applescript a long time ago and then moved on to other things. I'm now jumping back into scripting and don't know what I was thinking to have ever left.
This has to be the best and most productive lesson on JavaScript I’ve ever watched. I enjoyed it from start to finish and love the way he reiterates the important information. Even the remarkable introduction was an attention grabber. For those of you criticizing the slowness of this lesson, well that it so the average person can comprehend this esoteric part of JS. You can always increase the speed with UA-cam’s playback option. You just earned $20 from me brother.
***** watch your language mate, stay human and have a little respect for everyone it wont cost u anything, it is about equality it has nothing to do with feminism.
***** Poor guy, the bad feminists who stole your icecream, we ARE EVERYWHERE. How are you gonna live now? I wrote a comment saying a good thing, with a compliment, with nothing close to a "whining" and then there's some poor guy whining about whining feminists. Oh, the irony of it all. hahaha
It's like "ladys and gentlemen", it's about good manners, not feminism. He even should say "girls and guys", because himself is a guy, he shouldn't put himself first, to be really courteous. That being said... Death to feminism, it's pure ignorance.
Thank you, all the other tutorials I've come across just start by firing off code that means nothing to me. Understanding this has made everything so much easer. Thanks Tony!
I liked it at 1 because it gave my brain time to absorb what he was saying. It's nice to take it slow and let your mind do the learning with the aid of patience.
I had a lot of fun following the video through and bought the whole 11.5 hours package afterwards. I don't know exactly what it is that I appreciate about your course but your style of phrasing, rhythm of speak and focusing on the parts that are confusing for beginners is just awesome. Keep up the good work!
I bought this course and completed it today. He knows how to teach javascript clearly because he knows the engine that lies 'under the hood' very well :) .This course is far beyond of the other javascript courses. I hope he will record a new series and it covers much more advanced concepts. Thank you for your great effort.
Great work! I've looked at a few JS tutorials, both text and video, and none of them mention this kind of stuff. It's pretty scary when most guides don't even mention the fundamentals! Thanks for the video, I've already watched one half today and learn't a lot. : )
I was waiting to finish the whole video before I wrote any comments but I couldn't hold it anymore. I love you man. You are the best. I was really lost in javascript trying to apply concept from other languages that I already know, but you made it really really clear that js is a different animal. And for first time ever I know the reason behind my js codes. Everyone else on youtube teaches us just the syntax but you went above and beyond. Thank you sir. I never thought I would be this excited for JS. Thank You!!!!!
You Germans 😄😄😄 Tell everyone in Germany null is literally false, and not zero. I will help you if you need. Give me a, mailing list 😁 var x = Boolean(0 == false) console.log(x, "1. true 0 = false,") var newX = Boolean(null) console.log(newX, "2. boolean null is false, ") var y = Boolean(null == false) console.log(y, "3. null != false") var z = Boolean(null == 0) console.log(z, "4. null != 0")
WOOOOOOW. I had to sign in to comment on this video, and i never do that. Tony you are fr#$%ng incredible. I'm sure 5 yrs to come this video will still be useful to many. May God bless you for this
i am reading Crockford's ' JavaScript The Good Parts ', also a bit of ' Eloquent JavaScript ' by Marijn Haverbeke but your video really got me interested and i am only at 36th minute. :) I am definitely thinking about buying the whole course at udemy, but let me see the whole video you have here. Regards from Austria.
I think the best part of this video is your humble teaching style. You are very patient and thorough in your methods and it was sheer joy to listen and watch your video. Great job! I had a few "aha!" moments which pleasantly surprised me. Thank you!
only part that seems irrelevant in vid so far now is the var scope stuff. if u want some further info on scopes with let and const this is a grea page. jscomplete.com/learn/lab-functions-scopes
40:58 The reason why I love this tutorial. A lot of YT tutorials are misleading and inaccurate. Hoisting functions to the top just doesn't make sense especially when you have more than one function in that file.
I have watch tones of tutorials and this is the best I have seen. Just too good. Lots of concepts I have struggled with was perfectly explained. Thanks a million times. I can't Thank you enough Tony.
Holy shit. 36 minutes in and I've gained a better understanding than the rest of the stuff I've been trying to watch. This is exactly what I needed; someone who knows how to teach people who need to know the finer details of something in order to get their heads around it. I really your course is updated for 2021.

Just started the chapter on Functional Programming. I set the speed on 1.25 or 1.5 and then go over any parts I don't quite get the first time.
@@succeeder3044 isn't this the course that on YT. Or is there a different course? I'm still in the beginning phase of this video.
@@Ricebow11 this is just a quarter of the course. the remainder of it is in udemy and you can buy with coupons etc
I have to say when i forget anything related to JS, I always get back to this course it's really GOLD, Thanks Tony you really did a great job creating this course.
The first 3.5 hours have been so good, I just followed the link in the video description to Udemy for the full lecture list, and spotted exactly more of what I need explained -- I'm new to programming and JS and this is exactly what I need to better understand others' more advanced code. Thank you!
+Benjamin Millam Great, look forward to seeing you on the forums! Welcome!
You really hit the nail on the head at @11:00 I was one of those that were introduced to front end dev with all the frameworks and Jquery already in place. It was really hard for me to understand what's what.
I was in tutorial hell, until I watched this. Execution context cause the light bulb to light up so brightly. Thank you for putting this together!
This video is perfect. I'm a hobby web developer of 5 years and I'm about to attend a bootcamp and try to change my career permanently. This video is giving me a deeper understanding of JavaScript then I've ever had by far. Thank you so much!
In the world of programming someone finally takes the time to produce a help video that actually helps and doesn't just copy and paste the getting started page of into video format. Bravo!
This is well thought out and well produced and has a solid mission.. Understand how it works and you won't have to memorize every usage case.
The only criticism I can think of, and its not really a criticism, it the tempo of the narration.Its a bit slow but it does allow the consumer to think along the way.
Great content.
Great font size.
Great editor colors.
Great volume.
Just a pleasure to watch.
As i have ADHD and autism i still sat through a 3 hour video. That's probably because i love to code. Love to learn.
This is something i have a passion for. It stands out. Thank you for this.
This video was chosen out of many other tutorials that i could've chosen. I chose this one.
Thankssss
Swade What a great story Swade, keep it up and thanks for being a student!
It makes too much freaking sense i am telling you it makes too much sense i feel like i'm learn the alphabets all over again yo.
Exactly!

😂😂😂Loving your emphasy on how it makes sense
when you want to learn some thing... first respect the person who teach you, thank you.
Tony, I have really been struggling with the JavaScript. This video seemed to pull together everything I was struggling with and explain it in a new way that I can understand. Can’t wait to take the rest of the course. You have rejuvenated my excitement for wanting to learn JavaScript. Thank you Sir!!!!!
This is the BEST JAVASCRIPT TUTORIAL!!!! I was learning on freecodecamp, doing the exercises without understanding what the heck I'm doing. Tony explains each concept in detail and repeats the messages so that you can remember! Thank you thank you!!
this was by far the greatest Javascript tutorial I've ever seen. God bless the algorithm as well as this man for such a well explained and incredibly competent explanation of Javascript.
Long term suggestion: If you know anything else with even half the depth that you teach JS and Angular, you should do videos on those too - Linux shell, Databases - MySQL, NoSQL, Server Side languages - J2EE / Python / PHP. You know how to teach well. That skill / gift crosses technology boundaries.
This is how any thing should be taught :) Thank you
I concur
big like
I'm a Javascript developer for the past year and half. I feel fluent writing and reading it.
Just bought this course because it really grounds my intuitive understanding of this language, and extends my theoretical knowledge about it, eventually making me a better & complete developer.
I love this style of teaching. You have explained and ingrained fundamental JS concepts better than any other course. I've been struggling fully comprehending JS for months and this was just *BOOM* what I've been missing. Bought the Udemy course just now and am looking forward to finishing it. Thank you!
Bopy Tony you ain't kidding when you say that this is a very deep look inside Javascript! I have seen other JS tutorials but you REALLY probe deep into it.
Wow, you were born for this brother! Thank you, I'm checking this out now on Udemy!

Que diabos se passou .... nesse comentário .. "You Were BOM for this Brother".... amigo vai caçar u curso de ingles,,,,
Purchased your course today!! Once you started describing the objects, I new that this course was a great investment. Thank you very much for your course.
Can you provide me the full course ? ayazhussainbs@gmail.com
You need to have the right expectations for this course. It's an excellent collection of videos for you if you basically haven't spent any time with javascript at all yet, so you want to learn the fundaments as well as understand the weird parts. Tony takes the time to explain every small maybe 'obvious' fundamental multiple times, which is great if you're a complete novice to javascript. If you already have javascript knowledge and are excited about the weird parts and depths of this great language, the slow pace of the videos and multiple explanations of basic concepts as well as constant demoing in the console of stuff that you already know how it will look like, can be a bit tiring and forces you to constantly hit the skip 5 seconds button or set the playback speed to 1.25 or more. Like I said, just have the right expectations. This course is not only about the exciting weird parts - it's about those AND about all the basic fundamentals of the language, well explained to a high level of detail so that a person completely new to the language can understand it.
I can affirm for sure, this 3.5 hours make a lot more sense than many others pay courses for js fundamentals. I'm very impressed with the in depth explanation and professional approach. Thank you very very much for this truly hard and unique work.
officially the best coding course video i've seen. blessed, may you be showered with wealth so we can get the next 9.5 hrs for free.
Wish I could thank you in person. You the man Tony !!!
+Tyrese Hillr Thanks Tyrese!
sir .. how about this
function b() {
console.log(x)
}
function a() {
b()
}
a()
var x = 5
its return undifined ..
if the execution stop when a( ) is invoked then var x should be not exist in memory and its return eror ..
what i miss here in this course ??
Creation phase, memory space is set aside for var x, however it is not assigned the value of 5 yet.
Read up on Hoisting. Learning how the interpreter executes your code is important.
Tyrese Hillr I
This video now has chapters, which you can see in the video timeline as well at the bottom of the description. Thanks, and happy coding!
Is it suitable in 2020 ? for someone who wants to know more about JS?
This 3 hour course is so amazing! Understanding the global lexical environment and execution context is so important in regards to where things sit and how to understand how JavaScript works under the hood. I wish that this teacher had a million other videos!! I should have paid Tony the amount of money it took me to earn my degree in computer science. In three hours i understand more this topic than I did in four years.
Tony, a) I'm just about to buy your course and b) how lovely it would be to see what you make of ES6, and teach it to us. You are an outstanding teacher, and as such, a credit to the profession and to the species. No joke. Thanks for this work of art.
this is the best course in the world, Tony Alicea is the best teacher ever.
Every education workers/teachers need to learn from him!
after watching this for the third time in a row, i decided to get the course. i like the emphasis on the philosophy of javascript in order to better understand javascript as a whole. nicely done sir!
did you buy? was it worth it?
I doubt there's a better video to learn Javascript from. Beautiful explanation. (Tip: run at 1.25x)
As T. Reno says below, at 3 minutes in you said "Don't imitate. Understand." When I heard that I wanted to give my wall a hug (video projected).
Tony, I thank you from the bottom of my heart. THIS is the video I've been looking for... I'm a bit more than half way through and loving it. I used to write applescript a long time ago and then moved on to other things. I'm now jumping back into scripting and don't know what I was thinking to have ever left.
I completed this course 6 months ago, and while I don't fully know JS I do understand how it works. This course is worth any price tag
One hour into this and paused to go buy the course. Great way to promote it and thanks for the preview!

Much appreciated!
Thank you!
I fell asleep a year ago and woke to this video. It changed my life.
Hands down one of the best javascript course i have come across. Really makes it interesting and explains why the Javascript the way it is
Thanks so much, glad it has been helpful!
This has to be the best and most productive lesson on JavaScript I’ve ever watched. I enjoyed it from start to finish and love the way he reiterates the important information. Even the remarkable introduction was an attention grabber. For those of you criticizing the slowness of this lesson, well that it so the average person can comprehend this esoteric part of JS. You can always increase the speed with UA-cam’s playback option. You just earned $20 from me brother.
This video must be cursed or something, everyone wakes up to it on autoplay
just woke up to this
me too :)
at 3 minutes I am getting a VERY strong dejavu feeling
maybe thats why
good thing is i was able to build my own vr map now LUL
Bro i woke up to this last night
I'm still watching, but I just wanted to thank you for saying "guys AND girls". Thank you, for real.

***** watch your language mate, stay human and have a little respect for everyone it wont cost u anything, it is about equality it has nothing to do with feminism.
***** Poor guy, the bad feminists who stole your icecream, we ARE EVERYWHERE. How are you gonna live now?
I wrote a comment saying a good thing, with a compliment, with nothing close to a "whining" and then there's some poor guy whining about whining feminists. Oh, the irony of it all. hahaha
It's like "ladys and gentlemen", it's about good manners, not feminism. He even should say "girls and guys", because himself is a guy, he shouldn't put himself first, to be really courteous. That being said... Death to feminism, it's pure ignorance.
Y’all wake up to this? I put it on before sleeping better than any ASMR or podcast.
Thank you, all the other tutorials I've come across just start by firing off code that means nothing to me. Understanding this has made everything so much easer. Thanks Tony!
I am new to JavaScript, just started learning lexical scope and got recommended this video, I will watch it's entirety and take notes
I watched at 2x speed. Thanks, it was very interesting to find out some things I didn't know about javascript!
Thanks for your contributions to JS tutorials on UA-cam. Great job and very well organized!
Can you develop a dating app? I pay cash
Watching this at 1.25 speed is so much better
1.5 or 2 is better...he probably had to make it 12 hours so he just talked super slow.
1.5 was perfect for me.
I liked it at 1 because it gave my brain time to absorb what he was saying. It's nice to take it slow and let your mind do the learning with the aid of patience.
I leave it at 2 for parts that read like a book, and put it back to 1 for parts where you need to think about every word.
Thank you
I had a lot of fun following the video through and bought the whole 11.5 hours package afterwards.
I don't know exactly what it is that I appreciate about your course but your style of phrasing, rhythm of speak and focusing on the parts that are confusing for beginners is just awesome.
Keep up the good work!
I bought this course and completed it today. He knows how to teach javascript clearly because he knows the engine that lies 'under the hood' very well :) .This course is far beyond of the other javascript courses. I hope he will record a new series and it covers much more advanced concepts. Thank you for your great effort.
2:37:40
You know you write codes too darn much when you end a sentence in English with a semicolon;
:)
Hahaha
Thank you so much!!! You are an excellent teacher. I hope you continue to develop courses, preferably on everything ;)
Great work! I've looked at a few JS tutorials, both text and video, and none of them mention this kind of stuff. It's pretty scary when most guides don't even mention the fundamentals! Thanks for the video, I've already watched one half today and learn't a lot. : )
Agreed. The guy really knows what he’s talking about.
I was waiting to finish the whole video before I wrote any comments but I couldn't hold it anymore. I love you man. You are the best. I was really lost in javascript trying to apply concept from other languages that I already know, but you made it really really clear that js is a different animal. And for first time ever I know the reason behind my js codes. Everyone else on youtube teaches us just the syntax but you went above and beyond. Thank you sir. I never thought I would be this excited for JS. Thank You!!!!!
Watching till the end was so worth it. The last to chapters are so gold!!!
2:31:00 - Null is literally German for zero.
This exactly made me always confusing NULL and zero.
You Germans 😄😄😄
Tell everyone in Germany null is literally false, and not zero. I will help you if you need. Give me a, mailing list 😁
var x = Boolean(0 == false)
console.log(x, "1. true 0 = false,")
var newX = Boolean(null)
console.log(newX, "2. boolean null is false, ")
var y = Boolean(null == false)
console.log(y, "3. null != false")
var z = Boolean(null == 0)
console.log(z, "4. null != 0")
WOOOOOOW. I had to sign in to comment on this video, and i never do that.
Tony you are fr#$%ng incredible. I'm sure 5 yrs to come this video will still be useful to many.
May God bless you for this
i am reading Crockford's ' JavaScript The Good Parts ', also a bit of ' Eloquent JavaScript ' by Marijn Haverbeke but your video really got me interested and i am only at 36th minute. :) I am definitely thinking about buying the whole course at udemy, but let me see the whole video you have here.
Regards from Austria.
I've programmed for 30 years and have never seen a course that goes into this level of detail. Good job
I think the best part of this video is your humble teaching style. You are very patient and thorough in your methods and it was sheer joy to listen and watch your video. Great job! I had a few "aha!" moments which pleasantly surprised me. Thank you!
Who else watching in 2020 ?
only part that seems irrelevant in vid so far now is the var scope stuff. if u want some further info on scopes with let and const this is a grea page. jscomplete.com/learn/lab-functions-scopes

40:58 The reason why I love this tutorial. A lot of YT tutorials are misleading and inaccurate. Hoisting functions to the top just doesn't make sense especially when you have more than one function in that file.
That was an amazingly informative 3 hours, can't believe i sat through it in one go but I'm sure glad i did.
This is the single most important Javascript video if you truly want to deeply understand how Javascript works in both node and browser environments.
I have watch tones of tutorials and this is the best I have seen. Just too good. Lots of concepts I have struggled with was perfectly explained. Thanks a million times. I can't Thank you enough Tony.
I am rarely linking a video but this deserves a like from all my accounts
I wish someone to make a video just like this one, but about Python.. Great explaining, great video!
Just finish the whole course, it's just amazing !
Holy shit. 36 minutes in and I've gained a better understanding than the rest of the stuff I've been trying to watch. This is exactly what I needed; someone who knows how to teach people who need to know the finer details of something in order to get their heads around it.
I really your course is updated for 2021.
The best thing is when people are happy about your work . Ans that for me is eay more precious than earning money .
Thanks Man !
