Javascript Programming Tutorials, Guides & Best Practices

The Context API allows for sharing state across components without prop drilling. However, improper use can lead to performance issues, as any change in context value triggers re-renders in all consuming components.([Medium][6], [GeeksforGeeks][2])

Best Practices:

You can also split your code into smaller bundles that are loaded on demand. This is particularly useful for large applications with many routes or components.

import React, { Suspense } from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

const Home = React.lazy(() => import('./Home'));
const About = React.lazy(() => import('./About'));

function App() {
  return (
    <Router>
      <Suspense fallback={<div>Loading...</div>}>
        <Switch>
          <Route exact path="/" component={Home} />
          <Route path="/about" component={About} />
        </Switch>
      </Suspense>
    </Router>
  );
}

export default App;
