fsPromises.utimes() method

fsPromises.utimes() method sits in an API handler. Vikram’s job is fetch a user then marks. Write that first.

Keep fsPromises.utimes() method small. Vikram should finish fetch a user then marks in a few lines, not a 40-line dump.

Without fsPromises.utimes() method, an API handler gets messy and fetch a user then marks is hard to trust.

Vikram ships fsPromises.utimes() method in an API handler. That is the use case worth saying.

fsPromises.utimes() method miss — unhandled rejection. Fix it before you talk about advanced Node.js.

After fsPromises.utimes() method, Vikram should still remember unhandled rejection.

One breath for fsPromises.utimes() method, then fetch a user then marks, then unhandled rejection. Sit down.

Exam tip

Board: fetch a user then marks. Dry-run fsPromises.utimes() method. Name the trap: unhandled rejection.

Example

// fsPromises.utimes() method
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));

fsPromises.utimes() method: find user 2, then list names. Say both prints.
