What are some examples of modular programming in JavaScript?

Modular programming in JavaScript involves breaking code into smaller, reusable modules. For example, you can create a module for user authentication, another for data fetching, and so on. Would you like to see a specific example?

Yes, can you show me a simple example of a module?

Sure! Here's a simple example of a math module:

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

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

You can then import and use these functions in another file. Would you like to see how to import it?

Yes, please show me how to import and use it.

You can import the functions like this:

import { add, subtract } from './math.js';

console.log(add(5, 3)); // 8
console.log(subtract(5, 3)); // 2

This way, you keep your code organized and modular!
