TLS/SSL

TLS/SSL is a Node.js topic. In plain words you use it for a short TLS/SSL example in a script or API on localhost. Don’t start with a slogan — start with that picture.

Smallest example: the smallest TLS/SSL example you can type. Type it, run it, and say what you see. If you can do that from memory, you know TLS/SSL.

From the example next to this theory — TLS/SSL: find user 2, then list names.

Trap — only saying “TLS/SSL” with no example. Fix that before you talk about advanced Node.js.

Viva — what is TLS/SSL? Then show the smallest TLS/SSL example you can type. Then name the trap.

Exam tip

What is TLS/SSL? Show this: the smallest TLS/SSL example you can type. Trap: only saying “TLS/SSL” with no example.

Example

// TLS/SSL
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));

TLS/SSL: find user 2, then list names. Say both prints.
