Hi! I got errors. failed to load config from C:\Windows\System32\myfirstapp\vite.config.ts
error when starting dev server:
Error: EPERM: operation not permitted, open 'C:\Windows\System32\myfirstapp\vite.config.ts.timestamp-1679842359821.mjs'. How to fix this?
Please look into your payment method for the all access course monthyly subscription specifically the use of debit card.. It keeps declining my debit card, both visa and Mastercard. I'm from Nigeria.. I hope something is done about it so I can subscribe and learn. Thank you.
Hi Mosh, congratulations in this new course. When are you going to launch, the 2nd part?
hey mosh please upload intermidiate course of c++
which theme u use in vs code?
This was the most helpful thing in a while. Most you go thorugh the errors the same way we catch them. You dont just spoil the solution on why we are getting the error. So many times during this course when I got an error, I saw the hints that you gave and then tried to solve it on my own. Truly one of the best teachers!
Transitioning from backend to full stack development a few years ago. Been developing react apps for the last two years. I picked up several neat shortcuts and several key takeaways for a project I am building from scratch now. Thank you!
Hello bro I’m stuck at creating the development environment. Could you plz help me. Thanks
This course is so enjoyable to study. My past React experience (when I started using it for the first time) made me give up XD. But after a while, mastering JS in the meantime, I decided to come back, found this video and yeah, brings confidence back. Great video!
I'm a long time developer, but novice at web development. This tutorial was perfect for me. I appreciate how Mosh walks you through real development practices: incremental development cycles, using the IDE and tools, looking at errors, testing as you go. Thank you Mosh!
is this project mobile responsive?
Me too! Backend dev at the core, preparing for a full stack interview, and this tutorial is just great, I'm so excited!!
I didn't pressed liked this comment because it was 69. Let it be 🧐
Is this one hour course good enough for a sample project development?
It was not mentioned in the course, but I consider it important to mention that you should store the password or API key in the .env file as an environmental variable.
Your Courses are goldmine for me! Absolutely love the way you structure and deliver your courses with huge efforts.
Love the tutorial! Its the perfect balance of "show me the code" and "explain the concepts to me". Came here after a bunch of tutorials that jumped to deep into the code with no concepts or vice versa. Thankyou!
I'm an engineering manager recently hired into a full-stack team that uses React - this was a great taste of how React works to give me a better sense of it!
I did struggle to learn React. A lot of wasted time.
The problem? I did not know the basics of Javascript in first place. You need to walk before you can run.
So I took a few very basic books (books, not complex tutorials!) and learned the fundamentals.
After I learned the basics of Javascript, learning React became much easier.
Edit: For those asking about the books, for the very basics I learned with "Javascript In Less than 50 Pages".
And to develop my knowledge I learned with "Head First Javacript Programming".
True. I'm currently working on a node application where the frontent is completely in Vanilla JS, and I'm starting to get frustrated because my code starts to get messy and it all scales poorly. I think now is the right time to port everything to React, especially if I want other people to contribute. I don't want them to see my spaghetti code.
I think its a paid comment
@@mrfabulous3303 It is, don't trust this scam.
@@mrfabulous3303 It is a scam, the edit says "for those asking: literally no one asked LOL
Kudos for putting together such an excellent tutorial. This is one of the extremely rare instances where I went through an entire programming tutorial and everything actually worked! So many times I run into problems where things aren't working on my end the way they do in the tutorial, which forces me to spend a bunch of time trying to figure out what went wrong, mounting frustration, and ultimately just giving up. Really excited about incorporating React into my web development for enhanced user experiences!
Mosh's courses are the best way to learn. I love how he gives exercises so you can make sure you understood.
awesome Mosh. Your teaching style is concise and to the point. I am subscribed to a number of online IT learning resources but this is by far is the best intro to React that I went through.
Finally an updated version of React tutorial! I love your videos so much, but didn't want to invest in the other course since it was class based and outdated, now that you have an updated typescript function based tutorial I'm definitely buying this spring break. Keep making awesome, high quality videos mosh!
Hey bro,can you kindly share the React course when you buy it?, I am currently learning React,Mosh's course is great but it is so sad i can't afford to buy the course and i am currently in school,i am a student,i would be glad if you could share me the complete React course,await your response.

All these indians arguing 😆
This has to be the best hour and 20 minutes of learning on UA-cam! You are an excellent teacher! I hope you know how helpful and clear your style is.
Agreed. As a React newbie, I felt challenged as he introduced brand-new concepts back-to-back-to-back. Very information dense and little hand-holding. No verbose explanations on concepts we already understand. This is my kind of tutorial!
Thank you Mosh!
Thank you mosh!💌
I have my web paper after a day. This video is really helpful to study React with all the basic concepts for a beginner. Amazing!
I've been developing for a few years and your style of tutorials are some of the best that i've come across. Thank you!
Dude this tutorial is epic. I first started listening to it to check it out quick. It seemed understandable so i followed along over a few days and i'm not only understanding, everything is also sticking to my brain!!! thanks man
Hi Mosh thank you for yet another fantastic course. I checked through the full course and I noticed there isn’t any topic covering unit testing in this react course. I think this is a very important in modern react tool belt and would be helpful if you can look at adding it
Maybe it will be in part 2? Not sure.
I was wondering how you test react code
@@timSquash by using console.log('working'); lol
For everyone asking what theme he's using, its called "oh lucy"
tks you
🙏🙏
Please how can I get the continuietion of this course
@@user-bp8jq6fg2uyou can purchase or you can download it
Thanks bro. I am here for that same question and first comment is yours ❤
I love how you keep your code clean and explain every step as well as a few other ways to achieve the same goal. This helps a ton!
This is exactly the video I was looking for. I'm backend software engineer since 13 years, I want to progress on the frontend development but usually I found tutorial that are not detailed enough for me. Here it's really clear, put I my playlist and let's finished all my personal project which are working fine using postman but without any frontend ^^
Please include unit , integration and end to end testing for the part 2 of the course. That would really be helpful to develop robust react apps in the real world.
I was waiting for this course since last year, thank you so much Mosh, you're great teacher! thanks to you I've learn a lot and now I'm using it in my actual job! :') **big hug**
You're such a legend Mosh. This was my first completed react tutorial after several tries of grasping the concept. I even went ahead to make the button toggle the alert. And created other buttons to change the value of the main button from primary to warning to danger etc. It was great learning from you. Now onto real life projects from your website
I just finished the paid course and I must say it was great. I have been using regular/plain JavaScript for years and was holding out on learning React. This was a great introduction and was very digestible. Much love from Jamaica!
BRO AWESOME COURSE. I purchased the part 1 course and I have already finished it and now I am confident in coding websites. I am eagerly waiting for the part 2 course. I am also asking a request to make an updated React Native course with expo and routing and a full mobile application tutorial with firebase as backend. Keep up the hard work!! 👍
I was planning to follow a particular React tutorial but there's no other resources I can find except for one that uses react in the front-end. How fortunate I was in discovering this completely new 1 hour tutorial. Thanks man ya the real MVP.
Refer telusko bro django is different world
@@sivanarulanbu9252 I meant react jesus it's been a year already.
Just finished the full course! Hands down the best tutor!
Thanks Mosh!
I loved this tutorial because you didn't rush any explanations. You demonstrated everything and didn't leave much ambiguity in what's going under the hood.
Thanks man!
We have been waiting for this for a long time 😁
Hi Mosh, thank you for the great React course. I cant wait for the advanced topics. Are you able to share when we can expect the advanced course?
Thats an amazing course. I totally recommended. With detailed explanation, full of examples and exercises. In the end, there as an project, exemplifying everything learned.
This is great thanks!! I hope that every project will show us how to use different tools and react features :) Thank you Mosh
I loved this REACT tutorial! Your explanation and demonstration is perfect. Your exercises helped me test my understanding of what I had learnt. Once again a greater lecture and an even greater learning experience! Thanks a lot Mosh! Keep up the great content and wish you more success in the future!
Someone is considering changing fields
It came just in perfect time when I wanted to begin with react. Thank you.
same here the guy is a life saver
haha foreal. I was watching his from 4 years ago.. then I saw this. "huh he just made another one just a few hours ago, how convenient."
do need to purchase his course or this video and some projects are sufficient??
This is a very thorough and easy to understand tutorial, thanks so much Mosh!
This was incredibly helpful! Particularly getting my IDE set up to then work alongside GPT4/CoPilot... nothing can stop me now! :)
Thank you so much Mosh. I'm definitely purchasing this full course. I've been waiting for this since last year to help boost my skillset in my new phase.
Just purchased it. 👍

is this mobile responsive?
@@rakibislam463 I meant React JS, not native
@@dushananuradha1098 Bro, i understood what you're saying.But Don't you know when we make a project for a web,we have to also make it responsive for every device?
that's why I asked you If it is responsive.
Because I want to buy it.
@@rakibislam463 I got your question now. Be descriptive when you ask a question since the other person doesn't know what is in your mind. Pls note I just referred to this tutorial video, not the full course. There, he explained it using only web applications during the tutorial. Thus, have no idea about the course's relevance to mobile application dev.
I completed a short React course before coming to this video, and this video showed me more things that were skipped in that other course. Thanks
You're awesome Mosh! You're creating a great community with your videos and we appreciate you!
Thanks, lets see how well this prepared me for my job interview next week 🙌
33:00 when dealing with collections of simple items , you can use array.map( (item,index) => {}), the second argument to the map callback function returns the index of the element of the original array, then, you can simply set the key property using that index
I’ve done this before, too, but if you use index for your keys, and you say insert a new item in the middle of that array, then all the keys have to change when the component rerenders/reloads that block. Better to use keys that won’t change for a given item, no matter where it is in that array
This is a great course, well structured, not too fast and in depth explanations
The Ctrl + D shortcut to find the next occurrence of a word was such a neat trick! Really enjoying the lesson - thank you!
The biggest problem with this video is that it gets confusing and as a viewer I lose focus with the extra bootstrap, typescript and vite information instead of focusing just on REACT. I understand that these technologies are used in addition to REACT but for a complete newbie to REACT I find it hard to realize what is REACT code and what isn't. That being said I give this video an A+ for its content and delivery. Keep making great informational tutorials like this I love them!
Well that is React a big mess every developer pretends is enjoyable to code it.
@@jwoods9659facts. thanks for being honest. what’s the alternative?
@@jwoods9659 one and a half hour and 80+ packages installed + node and vite, variables that can not change a value using an equal (=) you have to use an updater function!! etc...all this to do something that you can do in 5 minutes with plain javascript... millennials in their maximum expression
I bought the full course a couple weeks back because I saw it was on sale. I've been enjoying it. Prior to this my only comparable experience was making a web app for a class that used just vanilla versions of HTML, CSS, JavaScript, and PHP. I'm liking how react comes together so far and have already been thinking I should try re-creating my class project using react.
I don't know if Mosh reads these comments very often, but if he does, I have just one critique for his classes. I wish he would wait for at least a count of two after he types some long line of code before hitting tab, switching over to another file, etc. Especially after he has typed something that he knows his students will be trying to type as well. There have been so many times where I've been trying to wait until he types the full line before pausing, but then I miss it because he immediately moves somewhere else. lol. It's a minor nitpick, but I thought I would mention it. Otherwise, I've liked how the course is set up and I'm looking forward to putting together the bigger project in the last section. :)
is this project mobile responsive?
Top video, it was like watching tv, loved how plain and simple you explained the concepts. Please keep posting more of this!
This made my "migration" from Angular to React very smooth!
Thanks 🙏
Mosh plz put more effort into ur youtube thumbnails. Masterpieces like this ought to be seen by more people ;)
Mosh, plz do me a favour. I simply love Svelte and think its the best but sadly it isn't very popular and doesn't have a large community. As a result, people and companies can't use it in their projects as much as they want to. I might be asking too much but I would really appreciate it if you could create a free Svelte course on youtube because I believe it will really raise Svelte's popularity and give it the attention it deserves. Love ur vids, keep the good work on.
Yes please Mosh. That would be wonderful.
Svelte is the best 💯
I’ll do my best!
@@programmingwithmosh Mosh, I don't know what to say. The fact that you listened to a random guy on the internet is simply amazing. I can't express my gratitude in words, so I won't make a mess of it. So stoked, love from India.
Svelte is SO FUCKING GOOD... I kinda want it to be a secret xD
once the video is posted by "mosh" you know that you are going to understand everything quickly... thanks for everything that you teach us... i hope you will never stop teaching cause you are a very good teacher.... much love.....
My first encounter was with mosh's React video from 5 years ago...and I belive its still on this channel...now that this is now out, using new react features, I will watch it all...and ofxourse share with my friends.
Hi Mosh,
When I started programming in 8th grade, your Java course was the first course I used to teach myself coding. Now, I am about to go off to college for my Bachelor's degree in Computer Science. Thank you for guiding me through this subject, I really appreciate it. Your tutorials have truly opened this world up for me.
Hi Arthur, I want to develop mobile applications, is react good for this? I am a little bit Confused between react and react native
@@xxcc5101 Hello,
I am no expert in mobile development (I'm more interested in machine learning), but React is typically for web development. React Native builds on React, and can be used for mobile development for both IOS and Android, as well as web development.
@@xxcc5101 Better learn Flutter for Mobile development
@@Mahmoud_176 can you say me why its better please?
@@xxcc5101 Because its the most used framework for mobile development nowdays
Super glad you went with TypeScript instead of JavaScript. TS really is the future, and every JS dev would benefit by incorporating it into their toolset.
Unnecessary bloatware...
Amazing! Thank you, I've learnt so so much. You make learning these things so engaging and clear.
you're a savior for uploading this right in time as I was learning react!!
Mosh thanks for the awesome course... Is this also include upcoming part 2? Or we have to purchase seperate part 2?
That’ll be a separate course.
@@programmingwithmosh Please I can't subscribe to any of your course, it keeps declining my debit card(mastercard and visa).. Please help out, it's saddening.
Mosh would you like to share the vscode theme you used in your course ?
I think its Material UI.
It's the "oh lucy" theme in extension marketplace
EXACTLY WHAT I NEEDED. THANKS SO MUCH
Thank you for "React Tutorial for Beginners", I love your explanation, and thanks that while playing your video series, I haven't seen an advertisement.
He cheats viewers by giving the wrong msg in thumbnail saying all the content in one video .. and he tries to push users to buy his course for the rest of the contest... Although Mosh is a great lecture but at the same time misleading the thumbnail and wasting users time dear mosh please do not do this!
@cricketknowledge5393 no
This is just an introductory course bro, take it easy. Anyone who knows anything about this stuff knows that an entire course cannot be completed in 1 hour 😂
1sr he didn't say full course!
2nd his courses are priceless. They worth every penny you pay
@@ouadieelouardy1171he state "you will learn REACT in 1 hour" :) you barely can start the development enviro in that time for the first time.
@@ouadieelouardy1171 2nd one isn't applicable to everyone. I also thought bro was providing everything from intro
I don't think this is a beginners course. You need to have some knowledge and be familiar with the concepts otherwise you're easily lost.
This is so awesome, thank you so much Mosh!
Thank you for making this course!! you are a very good instructor and explain things in a very easy manner!! I understood everything in no time!! Thank You!!❤
Don't tell me we have to buy the next part.
You have to. 😂😝
Well, check the description for full course.
Yes we have to

This was my very first tutorial for React and I loved it. I am a back end developer and I want to learn React.
Went to the website and purchased the course... hands down the best money I've ever spent.
Could you not have mentioned at the start of the video that the "Ultimate react course" you were talking about wasn't this video itself? That totally misleads people to think you'd be building and deploying that application within this course. Anyone reading this: **You have to pay for the actual 'Ultimate react course' and this video just isn't it**
Thank you Mosh, you are really good at teaching. I learned a lot from this tutorial and I like the extensions and shortcuts you recommend.
Supercool! I also released a crash course from React, but in Spanish and only with JavaScript. Your channel is very inspiring!
Brilliant tutorial, but some reasons why I downvoted:
1. False advertisement, the video thumbnail advertises "learn react 1 hour" and then the intro tells us how you are going to make this production grade app, so I invest in watching what you claim to elude that I will learn react in 1 hour and make this production grade app.
2. 20 minutes in, "oh btw this is actually a 8 hour course and you have to pay for the rest". Immediate dislike.
Aside from that this is a great video, high quality production and easy to follow, it's a shame you let yourself down so badly.
This was great!! Thanks for the update. A ton of things that make so much more sense now.
Looks great! Vite was a good choice for a modern react course. Hopefully that means we are one step closer to a NextJS course 🤞
Man this video is brilliant, I find it very helpful you go in depth when it's needed, but not so much to cover things that aren't really relevant, and then you challenge us to do something with the things we have learned as well as adding a bit extra forcing us to continue to learn. As I have always said about collage/uni, they aren't there to teach you everything there is to know about a subject, but share with you what they have learned and teach you how to continue to learn after the courses. You have great material. Keep it up!
The best thing I like from his contents that he provides a great overview review with the simplest explanation in 1-2 hours duration which is very easy to grab the basics which is the most required objectives for a software engineer to go for agile approach.
Thank you, just got a job that uses React and I needed a refresher. Great video!
Thank you Mosh. Easy to follow tutorial as always!
The soundtracks used in the video between different parts give a very positive vibe
Backend developer trying to be full-stack here. Best explanation of React concepts I've seen before. Thanks a lot!
That is a great overview. I walk through it, done all exercises and have a better understanding.
watched part of the other react video of yours yesterday. Great timing on this video!!
I became an avoidant to learn new things in dev cause not getting the explanation usually make feel anxious. Until I found your channel. And not just I understand rapidly, but already feeling the eagerness to learn more. Now that's something ! Thank you !!!
Bought the course. $20 for the best teacher. Great way to give a hour of content first and add value.
Saw your subscribe button flash with a sleek animation when you said to subscribe, thought "I'm in the right place"
this is probably one of the best tutorials so far, I just wished you went a little slower sometimes cause I had to stop and catch up with the code, but overall I understood like everything, so it worked! thank you
Finally, I was waiting long for this course on React
Whenever i want to get my hands on any new technology, i first check IF EXISTS in this channel .Thanks Mosh.
Thank you so much for this course, apt and very understandable
This is the most clear and concise basic ReactJS tutorial on UA-cam imo. A question though, what is the naming convention when we have multiple click events in the same component? "handleClick1", "handleClick2", etc looks really bad.
what a fantastic video thank you so much. so easier to follow than other videos out there
Wonderful content, clear, concise, and informative!
Thank you for the tutorial! I have a question, or rather, observation. At 55:02, basically the section of "Passing Functions Via Props" while understanding that we can pass functions through props is important. The example's result of logging the item's name into the console could be solved easily with adding 1 line after setSelectedIndex(index); that is: console.log(item); which essentially does the exact same thing :DD
Definitely not me trying to devalue your tutorial video, rather, I'm quite happy that I noticed I could do a little something with how little I know of React thus far.
Thanks for the video again!
Mosh, Thank you so much for this excellent tutorial.
As a Python Web developer on a studying stage sometimes I see mentions of React in job openings for fullstack development. Now it will no longer scare me, as it is with html/css/bootstrap collection.
By the way, I guess Django Template Language took {{ double curly braces }} only because {single ones} were reserved by JavaScript
Absolutely well defined and amazing content. Finally got something which is easy and quick video to refresh React.
the tutorial is so amazing its easy to follow THANK you Master Mosh! newbie here!
You are one of the best teachers which i have looked. Only necessary information without water. I am a backend developer, but with your lessons i plan to structure my knowledges about frontend and developer some pet project. And maybe i will try react native
Am new to React but after watching this i feel like a pro. Thanks Mosh and keep up the great content
I was struggling learning React. But this guy really a life saver. Even in his one hour video, he explains each and every single thing so well. I really appreciate your work and effort.
