React

React ranks as the most widely adopted JavaScript library, powering millions of websites and web applications. It is downloaded almost 20 million times per week from NPM, making it one of the most popular packages for frontend developers.

React is a component-based JavaScript library that enables developers to build user interfaces in a declarative manner. React components can range fromΒ simple togglesΒ to complexΒ dropdown navigations, or anything in between.


Why Should I Learn React?

Still, the question remains: why should I care about learning React? What's in it for me? Here are five reasons to help you decide whether you should invest your time in learning React:

Fun fact: The early prototype of React was called FaxJS.


Show Me How React Works

Let's take a look at a simple example to see how React works. To demonstrate conditional rendering and state management in one component, take the following code as an example. It renders a counter that can be set between 10 and -10:

import React, { useState } from 'react'

const App = () => {
    const [count, setCount] = useState(0);

    return (
        <React.Fragment>
            <h1>The current count is: {count}</h1>
            {count < 10 && (
                <button onClick={() => setCount(count + 1)}>
                    Increase
                </button>
            )}
            {count > -10 && (
                <button onClick={() => setCount(count - 1)}>
                    Decrease
                </button>
            )}
        </React.Fragment>
    );
}

export default App;
App.jsx

Where Should I Start?

If you are new to React, you should start with the basics. First, you need to familiarize yourself with JSX and its correlation to JavaScript. Next, start working with props and state to get a better understanding of the building blocks of components. This is the time when you also want to learn more about conditional rendering.

Once you are familiar with the basics, you can dive into usingΒ React hooks. When you are comfortable building all types of components, you can start exploring more advanced concepts, such as portals, lazy loading, or suspense. We also have a guided roadmap that teaches you everything you need to know about React.
