I do not understand why the function name "toggleTodo" return { ...todo, completed} in stead of { ...todo, completed:completed} ? because the e.target.checked return only true or false, then when we set the object property we need to specify the key, not just passing true or false, isn't it? Am I missing something?
I did struggle a lot to learn Rеact. A lot of time that I wasted. 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.
This tutorial is incredible. So many concepts in 40 minutes. For beginners, have a good grasp of JS function and how it's being passed around as if it's object. Thanks Kyle
I love how you dive right into features of React, making it clear why it is useful! I tried watching through the 12 hour freeCodeCamp React video, but by hour 4 I was thinking, "what is the point? This seems like so much more work for what I can already accomplish with JS."
Thanks! As a 1-month React developer, this video is amazing! for all the people who want to understand React basics for the first time, I low-key think the explanations are too fast
I agree, this could overwhelm you as a first timer, but if you've got some experience and still feel like you don't understand react, I think it's great.
Thanks for the tutorial; I've had to go over this several times, because, as others have mentioned in the comments, there is so much information in this tutorial. But things are making sense now. I love the fact that deleting elements is much simpler to do in React than in vanilla JS, just filter out the array element and it's gone after re-render. Looking forward to re-building some of my portfolio apps with React
Duuude! you are seriously one of the best Educators on this platform in regards to web development. Clear, concise, simple and engaging. I enjoy following your videos for projects, and always find myself picking one of yours. Thank you for your community contribution!
Simply amazing! I've watched a few more React videos but, even though they started from basics, they quickly jumped to a huge code which I wouldn't even be close to reproduce on my own. This video, instead, gave me clear use of state, hooks, modularization and basic structure. Great course!
Thank you Kyle, for this video! React's component driven approach is quite a shift from the top-down MVC architecture I'm used to. After about six weeks, though, of madly picking apart tutorial examples, getting a handle on hooks, and creating my own little "Frankenstein" React projects , things are finally starting to come together.
I like how I'm trying to code along and I'm attempting to code ahead of you, and every time i run into a certain mistake, you address it xD. Just goes to show how experienced you are at this.
Kyle, what a wonderful video - though I knew almost everything you were covering, there are many subtle ideas I grasped from your course that deepened my understanding of how React works. Your take on when to call setState with a function was definitely very insightful. I really loved the way you refactored your code and brought out props as a natural need - thank you so much.
Regarding 23:44: It's actually totally fine to use the non-function version of the state setter inside event handlers. The documentation specifically states this. Great video overrall!
Beautiful. Took me 5 days to follow step by step and build it in parallel and try to do things in a different way. Learned a lot about events, which I misunderstood initially
This was really great. I know JS and am familiar with Typescript and React. I was able to follow along in this tutorial and convert the JS to TS and get it all working! Super stoked and feeling like a I got a lot out of it.
Big fan from South Africa, Thank you for teaching us, I have learnt a lot from you, I basically learnt everything from your channel, Please come to South Africa
Great video, new to React and this channel - this is a well thought out example that really helps explain the concepts to a beginner , esp. the eventing/state and the component model all in one go - thanks very much!
Thank you for your dedication to teaching! I learnt the 'gist' of React, but I think it's my lack of JS that's holding me from understanding some parts of this video, like the use of parse in the JSON part in the end 39:45. Thank you for pointing out common beginner mistakes as well!
it's a pretty handy tutorial , in my perspective though i have noticed with quite a few videos is that sometimes you don't explain WHY certain things happen which makes things confusing. For example : the difference between doing setTodos([]) and using the functional form setTodos((currentTodo) => {return []}) . you dind't really explain why that the update in setTodos([]) will only actually take effect until the handler has been finished.
Really is the simplest React tutorial I've read to date, thank you. The only thing I still can't grasp is where you use the three dots e.g, ,,,todos I'm thinking about your course as this has been the best I've come across.
This is wonderful. Some of the stuff I struggled with were made so easy to under understand in this video (e.g. I was not aware you could pass functions through props). Man. You are a start. Thank you
It's one awesome video! I have learnt more here than other videos. You have explained so much that I was able to understand your all code. For me, the hardest part it comes when I try to build a simple application by myself. It takes me a lot of times that I have to think what and when I should first do. I'd love to hear some advice from you. Thank you, greeting from Poland!
Hi, Its part of the learning journey don’t get frustrated keep working on project that you “love” and care about just don’t get frustrated or discouraged after watching other senior devs figure out the things quickly. Don’t compare yourself with senior devs instead compare yourself with your own past self to feel motivated. Don’t give up anon!
The way to get over this is to begin diagramming in word, plaintext in a .txt file exactly what your project is and what it should do. First a high level description, then break down each part into a more precise description, then finally (in words) the logic for how you will build each part. Then code it up by following the steps you wrote out. The key is to separate the logic of the app from the actual writing of the code, this ensures that the task never becomes overwhelming. Good luck!
Hey Bro, to me you re one of the best english teacher of youtube. Your code is really clean and logic. I wish you could do a recent FullStack beginner free project with React/ tailwind / Redux. would be amazing.
I just finished watching this video and I have to say, it was incredibly helpful! The explanations were clear and concise, and I feel like I have a much better understanding of useState now. Thank you so much for sharing this valuable content.
I started by watching Typescript React tutorial (idk ts at all ) and as a newbie, I'm shocked at how much clearer and easier to understand Props are in Typescript when type is defined. Anyway great tutorial and thanks
I have got your React Simplified course . And I know React enough to build an app but this crash course is good for review and consolidating the essential concepts . Thanks!
I built the same app with TypeScript but I faced an issue with the css, where the checked property is not handled properly, when I click on the checkbox the state changes but the checkbox doesn't change (still not checked)...
Had the same issue even in JavaScript, changed from Firefox to Chrome and the checkbox now works fine. Either Firefox has a bug or Chrome supports a non-standard feature.
For anyone wondering why this isn't working and also didn't scroll far down the comments to see @jakob8797 comment, firefox doesn't support :has() yet which is used in one of the css selectors for the checkbox
I see what you have done here and I like it, using your personal blog as a middleman while rerouting to google but making sure the content over there is not just a piece of skipper text. The content covered was great but your explanations seemed incomplete and as if u wanted to finish it off as soon as possible. Great work despite that.
thank you jesus for actually telling people text labels are supposed to be clickable and the proper usage of the tag. Every time I use a webapp or form that doesn't allow you to click the text because the webdev didn't use a freakin label I die inside a little more.
Can someone explain the use of currentTodos, what is currentTodos and why was it not defined earlier, why do we need to use currentTodos instead of just working on todos
You are good at teaching but take a breath, we need to grab what you are telling. It is not that easy that you tell and we put that in our brain at the same time. Slow down a little. Thanks!
Hey Kyle, I see I'm not the only one with this issue: the custom checkbox doesn't render. Console log shows all expected values are getting returned, and commenting out the css on line 105 that hides the default list item check box pops up the default box in-line there and *that* box has expected behavior, so I'm assuming there's some issue on my end with your css that does "content: ""; on line 131... though in fact I see I can't get any of the display attributes for that custom checkbox to change on click. If you have time to comment on this it'd be a great learning experience...
I was quite impressed the way you explain things, when I saw some of your videos... So I gone to follow step by step to follow you... I am so eager to learn from you... After going through this video I will share my opinion , even though it will take me few days go through....Manohar
As usual awesome tutorial ! can you do please a tutorial on React Redux ? i would like love to hear your take on it ! and if you can explain what problem it solves, that would be great . Hope you have a good day.
Guess that’s just his typing speed. You can slow down the replay or pause the video. Maybe it’s the fact that Kyle does not slowbro himself through these tutorials that makes him able to make so much content for the rest of us.
Always love to see such comments. I can confirm it is css related. if you comment out the li css or just view the page without css checkbox works. seems to be a common problem with checkboxes and firefox, couldnt find the specific problem in css quickly. Some other post suggest looking into proton ui for firefox and that being the main issue.
Anybody else having an issue with checkboxes not checking in FIreFox? I tested it in chrome and it seems to work fine but in firefox nothing shows up even after removing all related styles
How come you used Vite? I'm used to running npm init react-app appname. Also, none of my files end in .jsx, they all end in .js. And when is your react simplified course going to be available? I only see a sign up form to be notified when it's ready.
Great crash course, although, probably worth noting that the checkboxes don't work in firefox. Works in chrome perfectly fine, spent too much time trying to debug nothing.
React is not a framework. It is a library. That is a HUGE difference, which leaves you with more organizational options. Getting that wrong didn't help your credibility.
