打包后的main.js是一段被压缩的JS代码,可阅读性呢不是很好,如果我们想看到更加可阅读性的JS代码,可以在webpack.config.js增加开发阶段的配置: module.exports={entry:{main:'./main.js'},mode:'development',optimization:{minimize:false} } 新增配置项mode=development,optimization.minimize被设置成false之后,再...

React是通过JS构建元素的, 我们都知道使用JS编写页面痛苦是没有结构性。 使用HTML两个标签能搞定的事,使用JS就能写一大堆代码。 React为了解决这个问题,提供了一个模板语言---JSX JSX是一种JS扩展语言。允许在JS中以标签形式构建元素。并且JSX开发工具中还可以具有各种提示和快捷键。 能够极大的提高开发效率 代码语...
This leads to improved code quality and robustness. Performance Optimization: React.js uses a virtual DOM to efficiently update and render components. JSX plays a crucial role in this optimization process by allowing React to perform efficient diffing (comparing and updating only the necessary parts)...

在RCTRootView.m文件里,initWithBridge初始化时会监听一系列的 JS 加载监听函数,监听到 JS Bundle 文件加载结束后,就会调用 JS 里的AppRegistry.runApplication(),启动 RN 应用。 分析到这里,我们发现RCTRootView.m只是实现了对RCTBridge的的各种事件监听,并不是初始化的核心,所以我们就又要转到RCTBridge这个文件上...

Step 2: Implement Code Splitting In the component where you want to apply code-splitting, use dynamic imports to load the components lazily. // App.js import React, { Suspense } from 'react'; const ComponentA = React.lazy(() => import('./ComponentA')); const ComponentB = React.lazy...
