How can I write modular code in Python and JavaScript?

How can I write modular code in Python and JavaScript?

To write modular code, you can use functions and classes to encapsulate functionality. In Python, you can create modules using .py files, while in JavaScript, you can use ES6 modules with import/export syntax.

Can you give me an example of a simple module in both languages?

Sure! In Python, you might have a file called math_utils.py with a function like def add(a, b): return a + b. In JavaScript, you could create a file mathUtils.js with export function add(a, b) { return a + b; }.

How do I use these modules in my main program?

In Python, you would use import math_utils and then call math_utils.add(2, 3). In JavaScript, you would use import { add } from './mathUtils.js'; and then call `add(2, 3);.

What are the benefits of writing modular code?

Modular code improves readability, reusability, and maintainability. It allows you to break down complex problems into smaller, manageable pieces.
