To implement lazy loading in a React application, you’ll rely on two things: ‘React.lazy()’ function and ‘Suspense’ component. These components hold a significant role in postponing the loading of specific websites. Let’s explore how we can use these react components to apply lazy load...
jsCopy codeconst MyComponent = React.lazy(() => import('./MyComponent'));这里的 import() 方法会返回一个 Promise，该 Promise 在组件代码加载完成后会 resolve，然后通过 React 渲染该组件。需要注意的是，由于异步加载组件的代码是在运行时执行的，而不是在构建时，因此需要使用符合 ECMAScript 标准的...
