semantic versioning

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

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

From the example next to this theory — semantic versioning: find user 2, then list names.

Trap — only saying “semantic versioning” with no example. Fix that before you talk about advanced Node.js.

Viva — what is semantic versioning? Then show the smallest semantic versioning example you can type. Then name the trap.

Exam tip

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

Example

// semantic versioning
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));

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