Smallest example: createReadStream. Type it, run it, and say what you see. If you can do that from memory, you know Difference between Node.js Buffers and Typed Arrays.

From the example next to this theory — Difference between Node.

Trap — loading the whole file into RAM. Fix that before you talk about advanced Node.js.

Viva — what is Difference between Node.js Buffers and Typed Arrays? Then show createReadStream. Then name the trap.

Exam tip

What is Difference between Node.js Buffers and Typed Arrays? Show this: createReadStream. Trap: loading the whole file into RAM.

Example

// Difference between Node.js Buffers and Typed Arrays
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));

Difference between Node.js Buffers and Typed Arrays: find user 2, then list names. Say both prints.
