In React apps, developers can implement various techniques to reduce the application’s overall footprint:
  
-   * Code Minification and Compression: By minifying and compressing JavaScript and CSS files, developers can significantly reduce their size, resulting in faster loading times and reduced bandwidth consumption. +   * Virtual DOM and Efficient Rendering: React’s virtual DOM efficiently updates and renders only the necessary components, reducing unnecessary re-renders and enhancing performance. 
-   * Lazy Loading: Implementing lazy loading techniques allows components, images, and other assets to be loaded only when they are required. This approach minimizes initial loading times and conserves bandwidth.+

-Improving performance not only enhances the user experience but also contributes to sustainability by reducing energy consumption. React provides several optimisation techniques that help improve application performance: 
- 
-   * Virtual DOM and Efficient Rendering: React’s virtual DOM efficiently updates and renders only the necessary components, reducing unnecessary re-renders and enhancing performance. 
- 
-   * Memoization and PureComponent: By memoizing expensive computations and utilising pure components, developers can prevent unnecessary calculations and re-rendering of components, leading to improved performance.
