path.isAbsolute() Method

path.isAbsolute() Method is a Node.js topic. In plain words you use it for join folder + file in Windows + Linux. Don’t start with a slogan — start with that picture.

Smallest example: path.join('notes', 'a.txt'). Type it, run it, and say what you see. If you can do that from memory, you know path.isAbsolute() Method.

From the example next to this theory: path.isAbsolute() Method — path.join builds OS-safe paths; extname reads the extension..

Trap — string concat with / only. Fix that before you talk about advanced Node.js.

Viva — what is path.isAbsolute() Method? Then show path.join('notes', 'a.txt'). Then name the trap.

Exam tip

What is path.isAbsolute() Method? Show this: path.join('notes', 'a.txt'). Trap: string concat with / only.

Example

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

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