vs PHP

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

Smallest example: the smallest vs PHP example you can type. Type it, run it, and say what you see. If you can do that from memory, you know vs PHP.

From the example next to this theory — vs PHP: find user 2, then list names.

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

Viva — what is vs PHP? Then show the smallest vs PHP example you can type. Then name the trap.

Exam tip

What is vs PHP? Show this: the smallest vs PHP example you can type. Trap: only saying “vs PHP” with no example.

Example

// vs PHP
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));

vs PHP: find user 2, then list names. Say both prints.
