How do I transition from non-modular to modular JavaScript?

Transitioning to modular JavaScript involves using ES6 modules or CommonJS. Are you familiar with these concepts?

I know a bit about ES6, but I'm not sure how to implement it.

You can start by using the import and export keywords. For example, export a function from one file and import it in another.

Can you give me a simple example?

Sure! In math.js, you can write export function add(a, b) { return a + b; }. Then in another file, use import { add } from './math.js'; to use that function.

That makes sense! What about older browsers that don't support ES6?

For older browsers, you can use a tool like Babel to transpile your ES6 code to ES5, ensuring compatibility.
