This is a gold mine. You really helped me grasp this concepts very well. Thanks!
This channel has one of the best JS videos! Keep doing.
Thank you for watching! :)
You're the best in explaining JS. Thx. I learn a lot of your videos.
Thanks for watching Patrick.
Best Of The Best , I Have ever seen
Thanks vivid explanation and easy to understand
man you break these thing down so well !!!
Thanks for watching! :)
Thank you sir, It is very helpfull
I like your videos. Very clear. FWIW, the class definition is much more clear than the constructor usage. Maybe it's just me, but it looks a lot more like what I would expect. I get that it is syntactic sugar, but it makes it more clear - at least to me.
I am glad that you got it. Classes are more intuitive than function constructors.
Good comparison Sir, Really helpful thank
Nice Explanation Sir!!!, Thank you very much...
Thank you for watching! :)
very help full to understand the behavior of JS.
Thank you for watching! :)
Yes, and functions are objects
Lovely tutorials. Thanks for making them. Could you do a series on javascript functional programming?
Osazeme, That is my plan to create a tutorial series on functional programming next. :)
Thanks
Nice tutorial. BTW, why do u need to create the constructor inside IIFE? We would have created the fn constructor without IIFE and still if you compare it with the class, it's gonna be the same right?
its not going to the same syntax wise I mean . IIFE plays an important role that.
Hi techsith how are you? I think it's been almost 2 months over since you upload video in UA-cam. I am big fan of your tutorial video. Hope you come with new video soon. Finally I am full stack developer. Node.js, React.js , mongoDb. I have a request. Is it possible for you to upload a video on binary search tree. Binary search tree was a title bit hard to understand. But I still remember you told one of your tutorial video about JavaScript that nothing is impossible to learn with techsith.
I am really excited to see you again
I am building a react series for udemy . its almost done. so starting next week i will be releasing more videos. Thanks for a reminder I do have plan for more react and nodejs videos. I may consider making videos on Binary search tree.
please provide a separate video tutorial in detail of ECMA? like what is ECMA script? difference in ECMA Script 2015,16,17 and 2018. how we can use it because in my recent interview in HCl, they have confused me in between ECMA scripts. so please also uploads the separate tutorials for this as the separate tutorials you have provided for Object-oriented JS and Prototype JS . Thanks in advance!.
Vinay, ECMA is a another name for javaScript. The the versions are ES5, ES6(ES2015), ES2016, and now ES2017. ES5 to ES6 was a big change where they introduced 'let', 'const' and some other cool features in javaScript. ES2016, ES2017 are smaller releses with few modifications to JavaScript. I will make a video explaing all this. bytheway here is a list of all the features that are changing.

techsith thanks, I'm waiting for your upcoming video
@@Techsithtube can you please provide link explaining journey n it's features of all es2015 n es2016 n es2017
sometime we define variable with __nariableName, What is the reason behind defining variable starting with __ ?
any convention like you declared car as let __car = function(color){}
usually, local/private variables are defined using underscore.
why are classes such a big deal that the EcmaScript standard decided to introduce them as syntactic sugar in JS. Also, may we know your name pls. it feels a bit impersonal to be addressing someone (from whom i'm deriving so much value) without knowing their name. Thanks.
Even though its a syntactic sugar. Its bit easier to use than ragular function constructors. My name is hemil patel
yes, they are.. i agree.. Thanks Hemil for this wonderful series.
hi can i create more than one constructor in a class in JS. Like one constructor having one parameter and another with no parameter.
+Dwipayan Tripathy in JavaScript arguments are optional so you don't need multiple constructors like java. Only one constructor is allowed.
techsith I think in Java,C#,C++. Infact in oops the argument is optional in the constructor. There we can use multiple constructor like we can say the constructor overloading.
JavaScript is very flexible . There is no need for constructor overloading.
I am using class Car in vscode editor throw this error ...Uncaught TypeError: Class constructor Car cannot be invoked without 'new'
Are you calling it like let Mycar = new Car ()
Then why we had to use Type script if all OOP concepts are available in Javascript ES2016
yeh true! I hate to write function constructor, class is more readable and easy to write!
