lodash.sortBy()

lodash.sortBy() (function) is a Node.js topic. In plain words you use it for a short lodash.sortBy function example in a script or API on localhost. Don’t start with a slogan — start with that picture.

Smallest example: the smallest lodash.sortBy function example you can type. Type it, run it, and say what you see. If you can do that from memory, you know lodash.sortBy() (function).

From the example next to this theory — lodash.sortBy(): find user 2, then list names. Say both prints..

Trap — only saying “lodash.sortBy function” with no example. Fix that before you talk about advanced Node.js.

Viva: what is lodash.sortBy() (function)? Then show the smallest lodash.sortBy function example you can type. Then name the trap.

Exam tip

What is lodash.sortBy() (function)? Show this: the smallest lodash.sortBy function example you can type. Trap: only saying “lodash.sortBy function” with no example.

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.
