What are the differences between lazy loading and code splitting in React and Vue?

Lazy loading is a technique to load components only when they are needed, while code splitting divides your code into smaller chunks that can be loaded on demand. In React, you can use React.lazy and Suspense for lazy loading, whereas Vue has built-in support for async components.

Can you give me an example of how to implement lazy loading in React?

Sure! In React, you can use the following code:

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

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

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

This will load LazyComponent only when it's rendered.

How does Vue handle code splitting?

In Vue, you can use dynamic imports to achieve code splitting. For example:

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

const routes = [
  { path: '/lazy', component: LazyComponent }
];

This will load LazyComponent.vue only when the route is accessed.

Which method is better for performance?

Both lazy loading and code splitting improve performance by reducing the initial load time. The choice depends on your specific use case. Lazy loading is great for components that are not immediately needed, while code splitting is useful for larger applications to manage bundle sizes.
