Factory Pattern in Node.js

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

From the example next to this theory — Factory Pattern in Node.

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

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

Exam tip

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

Example

// Factory Pattern 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));

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