Console

If you can teach Console using Console on Isha's board, you know it. If you only know the heading, you don’t.

Console order — meaning → one Console step Isha can write from memory → one limit. Dumping ten features helps nobody.

Console exists so Isha can keep Console on Isha's board correct in a small live site.

Console shows up in a small live site. Name Console on Isha's board, not “a real-world scenario”.

Don’t do this with Console — only reciting the name of Console. Interviewers spot it in ten seconds.

After Console, Isha should still remember only reciting the name of Console.

One breath for Console, then Console on Isha's board, then only reciting the name of Console. Sit down.

Exam tip

For Console: definition + a small live site + one failure.

Example

// Console
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));

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