ReactJS 是一种流行的JavaScript库，用于构建用户界面。它提供了一种声明式的编程模型，使得开发人员可以轻松地构建可复用的组件。ReactJS 还具有跨平台的能力，可以在不同的浏览器中运行。在本文中，我们将重点介绍 ReactJS 中的浏览器检测以及如何在不同浏览器中优雅地处理兼容性问题。

javascript
import React from 'react';
import ReactDOM from 'react-dom';
class App extends React.Component {
  componentDidMount() {
    if (typeof window !== 'undefined' && window.navigator) {
      if (window.navigator.userAgent.includes('Chrome')) {
        console.log('This is Chrome browser');
      } else if (window.navigator.userAgent.includes('Firefox')) {
        console.log('This is Firefox browser');
      } else {
        console.log('This is a different browser');
      }
    }
  }
  render() {
    return (
