<!DOCTYPE html>
<html lang=”en”>
    <meta charset=”utf-8″>
    <title > React UI Example </title >
    <div id=”root”> </div >
    <script src=””> </script>
    <script src=” react-dom/15.0.3/react-dom.min.js”> </script >

This includes Chrome, Firefox, Safari, Opera, and IE11+. Microsoft Edge does not yet have full React support, but recent versions have partial support. IE10 and below do not support React at all.



React is a popular JavaScript library that lets you build user interfaces quickly and easily. React is used in many high-quality web applications, so learning would be a wise decision if you’re ever interested in developing your web application. There are so many react hacks in 2022. we’ll teach you about React and how to get started with it.
