Inspector

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

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

From the example next to this theory — Inspector: find user 2, then list names.

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

Viva — what is Inspector? Then show the smallest Inspector example you can type. Then name the trap.

Exam tip

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

Example

// Inspector
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));

Inspector: find user 2, then list names. Say both prints.
