crypto.sign()

crypto.sign() (function) is simple if you keep it on paper. Asha uses it for a crypto.sign function dry-run in a viva board.

Keep crypto.sign() (function) small. Asha should finish a crypto.sign function dry-run in a few lines, not a 40-line dump.

Without crypto.sign() (function), a viva board gets messy and a crypto.sign function dry-run is hard to trust.

crypto.sign() (function) shows up in a viva board. Name a crypto.sign function dry-run, not “a real-world scenario”.

crypto.sign() (function) trap — only reciting the name of crypto.sign function. Asha loses marks for that every viva.

After crypto.sign() (function), Asha should still remember only reciting the name of crypto.sign function.

One breath for crypto.sign() (function), then a crypto.sign function dry-run, then only reciting the name of crypto.sign function. Sit down.

Exam tip

Board: a crypto.sign function dry-run. Dry-run crypto.sign() (function). Name the trap: only reciting the name of crypto.sign function.

Example

// crypto.sign()
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));

crypto.sign(): find user 2, then list names. Say both prints.

Short notes

Defcrypto.sign() (function) — Asha uses it for a crypto.sign function dry-run in a viva board.
Rulecrypto.sign() (function) → one crypto.sign function step Asha can write from memory.
Remembercrypto.sign() (function) + npm (a viva board).
