Stubs in Node.js

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

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

From the example next to this theory — Stubs in Node.

Trap — only saying “Stubs in node js” with no example. Fix that before you talk about advanced Node.js.

Viva — what is Stubs (in node js)? Then show the smallest Stubs in node js example you can type. Then name the trap.

Exam tip

What is Stubs (in node js)? Show this: the smallest Stubs in node js example you can type. Trap: only saying “Stubs in node js” with no example.

Example

// Stubs in Node.js
const users = [
  { id: 1, name: "Asha" },
  { id: 2, name: "Ravi" },
];

function findUser(id) {
  return users.find((u) => u.id === id) ?? null;
}

console.log(findUser(2));
console.log(users.map((u) => u.name));

Stubs in Node.js: find user 2, then list names. Say both prints.
