semantic versioning

Don’t start semantic versioning with jargon. Start with Neha walking through semantic versioning. That is the whole point.

Do semantic versioning once by hand. one semantic versioning step Neha can write from memory. Change one input. Say the new result out loud.

Without semantic versioning, a first job task gets messy and Neha walking through semantic versioning is hard to trust.

Use semantic versioning when Neha walking through semantic versioning must stay clear. If a simpler Node.js step works, use that instead.

If Neha walking through semantic versioning breaks under semantic versioning, check copy-pasting semantic versioning without a dry-run first.

After semantic versioning, Neha should still remember copy-pasting semantic versioning without a dry-run.

Close semantic versioning with: “If I skip it, Neha walking through semantic versioning goes wrong like this: copy-pasting semantic versioning without a dry-run.”

Exam tip

Board: Neha walking through semantic versioning. Dry-run semantic versioning. Name the trap: copy-pasting semantic versioning without a dry-run.

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.
