This is a relaunch of my existing course, The Road to Learn React. A lot has changed in React since I first created this course, and so here I am to give you all the information you need to work with modern React. (If you’re looking for content on legacy React, the old course is still available as well.)

In this course you will take a deep dive into React fundamentals, covering all new React concepts including Hooks. I do address some legacy features in case you’re working with an older codebase, but the majority of this course will focus on working with modern React. You will learn how to style your app, techniques for maintaining your app, and some more advanced concepts like performance optimization.

Throughout the course, you will gain hands-on experience by building a Hacker News app, and by the end of this course, you will be prepared to build your own applications and have something to showcase in your portfolio.

The Road to React: The One with Hooks

The App component has been in our application from the start, in the *src/index.js* file:

import React from 'react';
import ReactDOM from 'react-dom';

import App from './App';

ReactDOM.render(
  <App />,
  document.getElementById('root')
);

Next to React, there is another imported library called `react-dom`, in which a `ReactDOM.render()` function uses an HTML node to replace it with JSX. The process integrates React into HTML. `ReactDOM.render()` expects two arguments; the first is to render the JSX. It creates an instance of your App component, though it can also pass simple JSX without any component instantiation.

Now that we've learned about component definitions and their instantiation, we can move to the App component's instantiation.
