When should you use modules (import/export)?

Modules in JavaScript are a powerful feature that allows you to break your code into separate files, promoting better organization and reusability. You should consider using modules (import/export) in the following scenarios:

When you have dependencies that need to be shared across multiple files.
To keep your codebase clean and maintainable by encapsulating related functionality.
When you want to avoid polluting the global scope.
To facilitate testing and modularity.

Using the import/export syntax, you can import specific functions, classes, or variables from other modules, making it easier to manage your code.


        // Example of a JavaScript module
        // math.js
        export function add(x, y) {
            return x + y;
        }

        export function subtract(x, y) {
            return x - y;
        }

        // main.js
        import { add, subtract } from './math.js';
        console.log(add(5, 10));  // Output: 15
        console.log(subtract(10, 5));  // Output: 5
