Process

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

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

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

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

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

Exam tip

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

Example

// Process
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));

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