Zara ships lodash.sortBy() (function) in a first job task. That is the use case worth saying.

lodash.sortBy() (function) miss: skipping the failure case for lodash.sortBy function. Fix it before you talk about advanced Node.js.

lodash.sortBy() (function) is not a lonely heading. Zara ties it to lodash.sortBy function on Zara's board.

Exam tip

Say lodash.sortBy() (function) in one breath, then one lodash.sortBy function step Zara can write from memory, then skipping the failure case for lodash.sortBy function.

Example

// lodash.sortBy()
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));

lodash.sortBy(): find user 2, then list names. Say both prints.
