Garbage Collection in Node.js

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

From the example next to this theory — Garbage Collection in Node.

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

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

Exam tip

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

Example

// Garbage Collection 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));

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