os.arch() Function in Node.js

os.arch() Function (in node js) is a Node.js topic. In plain words you use it for print OS type in a tiny script. Don’t start with a slogan — start with that picture.

Smallest example: os.platform() / os.homedir(). Type it, run it, and say what you see. If you can do that from memory, you know os.arch() Function (in node js).

From the example next to this theory — os.arch() Function in Node.js: find user 2, then list names. Say both prints..

Trap — hard-coding C:\\ paths. Fix that before you talk about advanced Node.js.

Viva — what is os.arch() Function (in node js)? Then show os.platform() / os.homedir(). Then name the trap.

Exam tip

What is os.arch() Function (in node js)? Show this: os.platform() / os.homedir(). Trap: hard-coding C:\\ paths.

Example

// os.arch() Function 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));

os.arch() Function in Node.js: find user 2, then list names. Say both prints.
