Process

Process is simple if you keep it on paper. Meera uses it for Meera walking through Process in a first job task.

Do Process once by hand. one Process step Meera can write from memory. Change one input. Say the new result out loud.

Process exists so Meera can keep Meera walking through Process correct in a first job task.

Use Process when Meera walking through Process must stay clear. If a simpler Node.js step works, use that instead.

Process miss — copy-pasting Process without a dry-run. Fix it before you talk about advanced Node.js.

Process is not a lonely heading. Meera ties it to Meera walking through Process.

Viva for Process: what it is → one Process step Meera can write from memory → the mistake (copy-pasting Process without a dry-run).

Exam tip

Say Process in one breath, then one Process step Meera can write from memory, then copy-pasting Process without a dry-run.

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.
