Create Database

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

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

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

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

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

Exam tip

What is Create Database (mysql)? Show this: the smallest Create Database mysql example you can type. Trap: only saying “Create Database mysql” with no example.

Example

// Create Database
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));

Create Database: find user 2, then list names. Say both prints.
