Performance Optimization with Lazy Loading

Pascual Vila

Frontend Instructor.

Lazy Loading is an optimization technique that allows components or resources of a React application to be loaded only when they are needed. This is especially useful for large applications with many routes or components, as it reduces the initial loading time by splitting the code into "chunks" or fragments.

Implementing Lazy Loading in React:

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

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

function App() {
  return (
    
      My Application with Lazy Loading
      Loading...}>

); } export default App;`}

In this example, LazyComponent will only be loaded when needed. Suspense is used to display a loading indicator while the component is being downloaded.
