Say util.types.isMap() Method in one breath, then one util.types.isMap Method step Asha can write from memory, then skipping the failure case for util.types.isMap Method.

Example

// util.types.isMap() 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));

util.types.isMap() Method: find user 2, then list names. Say both prints.
