Pagination in Node.js

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

Smallest example: the smallest Pagination node js example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Pagination (node js).

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

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

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

Exam tip

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

Example

// Pagination 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));

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