join()

join() (function) is a Node.js topic. In plain words you use it for a short join function example in a script or API on localhost. Don’t start with a slogan — start with that picture.

Smallest example: the smallest join function example you can type. Type it, run it, and say what you see. If you can do that from memory, you know join() (function).

From the example next to this theory — join() — path.

Trap — only saying “join function” with no example. Fix that before you talk about advanced Node.js.

Viva — what is join() (function)? Then show the smallest join function example you can type. Then name the trap.

Exam tip

What is join() (function)? Show this: the smallest join function example you can type. Trap: only saying “join function” with no example.

Example

const path = require("path");
const full = path.join("users", "asha", "docs");
console.log(full);
console.log(path.extname("report.pdf"));

join() — path.join builds OS-safe paths; extname reads the extension.
