fsPromises.lstat() Method

fsPromises.lstat() Method is a Node.js idea you prove with fetch a user then marks, not with a slogan.

fsPromises.lstat() Method order — meaning → async function + try/catch → one limit. Dumping ten features helps nobody.

fsPromises.lstat() Method exists so Neha can keep fetch a user then marks correct in an API handler.

Neha ships fsPromises.lstat() Method in an API handler. That is the use case worth saying.

If fetch a user then marks breaks under fsPromises.lstat() Method, check unhandled rejection first.

Place fsPromises.lstat() Method next to nearby Node.js work — async function + try/catch is the link.

Close fsPromises.lstat() Method with: “If I skip it, fetch a user then marks goes wrong like this: unhandled rejection.”

Exam tip

For fsPromises.lstat() Method: definition + an API handler + one failure.

Example

// fsPromises.lstat() 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.lstat() Method: find user 2, then list names. Say both prints.
