Learning JavaScript libraries and frameworks can be overwhelming. There are many libraries to choose from, and no proper step-by-step guides that’ll teach you how to use these libraries to their fullest potential. That’s why, in this video, you’ll learn the most popular JavaScript library, used by hundreds of thousands of developers worldwide - React.js.
If you want to learn everything from the essential JSX syntax all the way to more advanced React topics, like state, hooks, data fetching, and more, you’ve come to the right place. Most importantly, I’ll teach you how to build a React.js application so that you can actively internalize and independently apply everything you’ve learned in this beginner-friendly React Crash Course video.

[@jakob_mierscheid]

I'm in a code camp at the moment and half-way through the video I can already say: The way you point out certain basic principles and good practices seem (1) very logical and undestandable to me. And (2) you explain it in a more structured way than my teachers at codecamp. Thanks for taking the time to explain this in detail.

[@qbwoa]

Thank you, Andrian. This is absolutely my first react project and the first time I got to understand the concepts. You are a great teacher.

[@marythompson9116]

This was the best tutorial I've tried so far. I made it all the way to the end without giving up AND I was even using a mock api from json file I create for video games instead of movies as I was learning minimal API at the same time and everything worked out great! Thanks a lot for this.

I'm a seasoned backend and cloud engineer, and I've never really cut my teeth on front end development before. This guide was fantastic at filling in some of the gaps I had after an initial read of the React documentation. Thanks!

[@gime1945]

I never realized how helpful the actual visualization of the concepts would be. Thank you for that. It definitely improves the learning experience for a lot of us, and it's far better than just hearing someone talk.

Having worked with React some time ago, I recently found myself in need of a refresher to jog my memory on its core concepts and best practices. This video served as the perfect recap, succinctly summarizing all the essential knowledge I had gathered over time. It's impressive how it managed to cover both the basics and some nuanced details, making it invaluable for both beginners and those looking to revisit React after a break. Thank you for creating such a comprehensive and insightful resource. It's clear a lot of effort went into making this content accessible and engaging, and it certainly paid off. Great work! 👏👏👏

[@hcutter9802]

As someone struggling to get my head around React, this is by far the best tutorial I've found anywhere online. Well done.

[@johngoutung1229]

I did struggle a lot to learn React. Wasted a lot of 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".

2 years later and this tutorial is still valid! I used the latest version of react so, my Index.js looked different... But everything else in the tutorial worked like a charm! I also had an issue with my search, when I searched a new movie it would reset back to the useEffect() setting of the batman... but i quickly realised that it was cause i never gave it and empty array lol. Anyways great video! Just downloaded the roadmap now!

@Andrain, When I started to watch your tutorial, immediately after 5mins I hit 'Subscribe'😂 Your teaching style and content delivery is simply superb!! When you created a single card with just one raw movie data, it made more sense to understand components, props, reusability, so on,.. very effectively!! In fact when I started, I was very sleepy! But once I started, I didn't stop until I finished the App!! Thanks a lot ❤❤❤

Done thanks 21:30 react jsx allows you to use JavaScript inside your “html” like a templating language. Expressions inside { } are evaluated as JavaScript code. 22:50 can conditionally render HTML components in jsx by placing them in curly braces to be evaluated as js Props passes to components through html attributes in jsx. The component catches the props object in its function definition (using functional components as class bases components are deprecated) Managing state variables with the usestate hook which returns a tuple, the variable that represents state item and a setter method. The setter method MUST be used to change the value of the state variable in order for react components to see the change You apply css files by importing them on top of your react component useEffect hook allows you to trigger a callback when a state variable changes (must be changed with the state setter given by useState). You can give useEffect array of dependencies (state variables), if empty array then useEffect triggered when the component loads only

[@sundayagu5755]

God bless you. I got it to work for me. The major issue I had was that: my react version was 18.0 but yours was 17.2. Version 18.0 does not support React-dom render(), which is now a legacy root API. For those that may encounter a similar problem, The new root API uses createRoot.. This is the code I used: import * as ReactDOMClient from 'react-dom/client'; import App from './App'; const container = document.getElementById('root'); const root = ReactDOMClient.createRoot(container); root.render();
