What are some examples of modular code in JavaScript?

Modular code in JavaScript refers to writing code in separate, reusable modules. For example, you can create a module for handling user authentication.

Can you show me a simple example of a module?

Sure! Here's a basic example:

// user.js
export function getUser(id) {
    return { id, name: 'John Doe' };
}

// main.js
import { getUser } from './user.js';
const user = getUser(1);
console.log(user);

What are the benefits of using modular code?

Using modular code improves maintainability, reusability, and testability. It allows developers to work on different modules independently.

How do I organize my modules in a project?

You can organize modules by functionality or feature. For example, you might have folders for components, services, and utilities.
