How can I implement lazy loading in React and Vue?

Lazy loading is a design pattern that delays the loading of resources until they are needed. In React, you can use React.lazy and Suspense for this. In Vue, you can use dynamic imports with the component option.

Can you show me a code example for React?

Sure! Here's a simple example:

import React, { Suspense, lazy } from 'react';

const LazyComponent = lazy(() => import('./LazyComponent'));

function App() {
  return (
    <Suspense fallback={<div>Loading...</div>}>
      <LazyComponent />
    </Suspense>
  );
}

What about Vue? How do I do it there?

In Vue, you can use the following syntax:

const LazyComponent = () => import('./LazyComponent.vue');

export default {
  components: {
    LazyComponent
  }
};

Are there any performance benefits to lazy loading?

Yes, lazy loading can significantly improve the initial load time of your application by reducing the amount of code that needs to be loaded upfront.
