Create Database

Create Database (mysql) is a Node.js idea you prove with Create Database mysql on Riya's board, not with a slogan.

Keep Create Database (mysql) small. Riya should finish Create Database mysql on Riya's board in a few lines, not a 40-line dump.

Without Create Database (mysql), a viva board gets messy and Create Database mysql on Riya's board is hard to trust.

Create Database (mysql) shows up in a viva board. Name Create Database mysql on Riya's board, not “a real-world scenario”.

Create Database (mysql) trap — only reciting the name of Create Database mysql. Riya loses marks for that every viva.

Place Create Database (mysql) next to nearby Node.js work — one Create Database mysql step Riya can write from memory is the link.

Close Create Database (mysql) with: “If I skip it, Create Database mysql on Riya's board goes wrong like this: only reciting the name of Create Database mysql.”

Exam tip

Board: Create Database mysql on Riya's board. Dry-run Create Database (mysql). Name the trap: only reciting the name of Create Database mysql.

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.
