Reactjs tutorial for beginners


Configuration Option 1: Type the code in the browser
This is the fastest way to get started!

First open this start code in a new tab. The new tab should show a rowed game board and a reaction code in the empty table. We will edit the react code in this tutorial.

You can now skip the second setting and go to the overview section to get a general description of the response.

Configuration Option 2: Local development environment
This is completely optional and not required for this tutorial!


Optional: Instructions for implementing it locally using your favorite text editor
Help, I'm stuck!
If it gets stuck, consult community support resources. In particular, Reactiflux chat is a great way to get help quickly. If you do not receive an answer, or if you are stuck, submit a problem and we will help.

Overview
Now that it's been created, let's take a look at React Reaction!

What is the reaction?
Is a declarative, efficient and flexible JavaScript library for building feedback interfaces. It allows you to compose complex user interfaces with small, isolated code pieces called "components".

There are several different types of reactants, but we will start with the react. Subclass of components:

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

class Test extends React.Component {
  render() {
    return <h1>Hello World!</h1>;
  }
}

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