Punycode

Punycode is simple if you keep it on paper. Sara uses it for a Punycode dry-run in a first job task.

Punycode on the board — one Punycode step Sara can write from memory. Then say what a Punycode dry-run looks like after.

Without Punycode, a first job task gets messy and a Punycode dry-run is hard to trust.

Use Punycode when a Punycode dry-run must stay clear. If a simpler Node.js step works, use that instead.

If a Punycode dry-run breaks under Punycode, check only reciting the name of Punycode first.

Place Punycode next to nearby Node.js work — one Punycode step Sara can write from memory is the link.

One breath for Punycode, then a Punycode dry-run, then only reciting the name of Punycode. Sit down.

Exam tip

Say Punycode in one breath, then one Punycode step Sara can write from memory, then only reciting the name of Punycode.

Example

// Punycode
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));

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