View Engine in Node.js

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

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

From the example next to this theory — View Engine in Node.

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

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

Exam tip

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

Example

// View Engine 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));

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