What are the differences between modular and non-modular JavaScript?

What are the differences between modular and non-modular JavaScript?

Modular JavaScript organizes code into separate files or modules, promoting reusability and maintainability. Non-modular JavaScript typically involves a single file with all code, which can lead to difficulties in managing larger applications.

What are the benefits of using modular JavaScript?

Benefits of modular JavaScript include improved code organization, easier debugging, and the ability to reuse code across different projects.

Can you give me an example of a modular JavaScript structure?

Sure! A common structure involves using ES6 modules, where you can export functions or variables from one file and import them into another, like this:

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

// main.js import { add } from './math.js'; console.log(add(2, 3)); // Outputs: 5
