The first step to getting familiar with a new language is to write a simple “Hello World” program. React JS is an open-source JavaScript library for building user interfaces (usually for single-page applications).
In the code below, you need to import React
by using this command:
import React from `react`
Then, import ReactDOM
for the render()
function in which the HTML code is specified.
A style sheet can be used for the specified HTML code as well.
import React from 'react'; require('./style.css'); import ReactDOM from 'react-dom'; ReactDOM.render( <p>HelloWorld!</p>, document.getElementById('root') );
