Assert Module

Theory

59/723

Assert Module is a Node.js idea you prove with install express, not with a slogan.

Keep Assert Module small. Rohit should finish install express in a few lines, not a 40-line dump.

Skip Assert Module and deleting package-lock blindly shows up in a new folder.

Assert Module shows up in a new folder. Name install express, not “a real-world scenario”.

Assert Module miss — deleting package-lock blindly. Fix it before you talk about advanced Node.js.

Assert Module is not a lonely heading. Rohit ties it to install express.

Close Assert Module with — “If I skip it, install express goes wrong like this: deleting package-lock blindly.”

Exam tip

For Assert Module: definition + a new folder + one failure.

// math.js style
function add(a, b) { return a + b; }
module.exports = { add };

const math = { add };
console.log(math.add(2, 3));

Assert Module — commonJS uses require / module.exports. ESM uses import / export.
