Mocha in Node.js

Mocha (in node js) is a Node.js topic. In plain words you use it for a short Mocha 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 Mocha 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 Mocha (in node js).

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

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

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

Exam tip

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

Example

// Mocha 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));

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