Delete Record

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

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

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

Trap — only saying “Delete Record mysql” with no example. Fix that before you talk about advanced Node.js.

Viva: what is Delete Record (mysql)? Then show the smallest Delete Record mysql example you can type. Then name the trap.

// Delete Record
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));
