What are the best practices for using modules in JavaScript?

Some best practices include using ES6 import/export syntax, keeping modules small and focused, and avoiding global variables.

Why is it important to keep modules small and focused?

Keeping modules small and focused enhances readability, maintainability, and reusability, making your code easier to manage.

Can you give an example of a well-structured module?

Sure! A well-structured module might look like this:

// math.js
export function add(a, b) {
    return a + b;
}

export function subtract(a, b) {
    return a - b;
}

This module exports two functions, keeping it simple and focused.

What should I avoid when creating modules?

Avoid using global variables, tightly coupling modules, and creating large monolithic modules. These practices can lead to code that is hard to maintain.
