JavaScript Modules
メニューを表示するにはスワイプしてください
As applications grow, writing all code in a single file becomes hard to manage.
Modules allow you to split code into multiple files and reuse it where needed.
You can export values from one file:
// math.js
export const add = (a, b) => a + b;
And import them in another file:
// app.js
import { add } from "./math.js";
console.log(add(2, 3));
This keeps code organized and makes it easier to maintain.
Modules are widely used in backend development to separate logic, utilities, and features into different files.
