How can JavaScript code be modified to replace server-side data loading with static data stored in a file system for better performance?

When replacing server-side data loading with static data stored in a file system for better performance, you can create a JSON file containing the data and load it directly in the JavaScript code. This eliminates the need for server requests and reduces the load on the server, resulting in faster loading times for the web application. ```javascript // Load static data from a JSON file fetch('data.json') .then(response => response.json()) .then(data => { // Use the data in your application console.log(data); }) .catch(error => { console.error('Error loading data:', error); }); ```
