React

React is a library by Facebook.

• Uses JSX

import React, { Component } from 'react';

class App extends Component {
  render() {

    return (
      <div className="App">
        Hello World!
      </div>
    );
  }
}

export default App;

• Many good Patterns: Single Responsibility, DRY, abstraction of state

Let's create an app!

npm install -g create-react-app

create-react-app my-app
cd my-app/
npm start
