Caching in Node.js

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

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

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

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

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

Exam tip

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

Example

// Caching 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));

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