When should I use ES6 modules?

What are ES6 modules and when should I use them?

ES6 modules are a way to structure JavaScript code by exporting and importing functions, objects, or values. You should use them when you want to organize your code better, avoid global scope pollution, and enable code reuse.

Can you give me an example of how to use ES6 modules?

Sure! You can create a module by using the export keyword. For example, in a file named math.js, you can write: export function add(a, b) { return a + b; }. Then, in another file, you can import it using: import { add } from './math.js';.

Are there any downsides to using ES6 modules?

One downside is that ES6 modules are not supported in older browsers without a transpiler like Babel. Additionally, they can introduce complexity in small projects where simple scripts might suffice.

When should I avoid using ES6 modules?

You might want to avoid ES6 modules in very small scripts or when working in environments that don't support them, like some older browsers or certain Node.js versions without proper configuration.
