MongoDB Sorting

MongoDB Sorting is a Node.js idea you prove with MongoDB Sorting on Arun's board, not with a slogan.

Keep MongoDB Sorting small. Arun should finish MongoDB Sorting on Arun's board in a few lines, not a 40-line dump.

MongoDB Sorting exists so Arun can keep MongoDB Sorting on Arun's board correct in a small live site.

Arun ships MongoDB Sorting in a small live site. That is the use case worth saying.

MongoDB Sorting trap — skipping the failure case for MongoDB Sorting. Arun loses marks for that every viva.

MongoDB Sorting is not a lonely heading. Arun ties it to MongoDB Sorting on Arun's board.

Viva for MongoDB Sorting: what it is → one MongoDB Sorting step Arun can write from memory → the mistake (skipping the failure case for MongoDB Sorting).

Exam tip

Board: MongoDB Sorting on Arun's board. Dry-run MongoDB Sorting. Name the trap: skipping the failure case for MongoDB Sorting.

Example

// MongoDB Sorting
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));

MongoDB Sorting: find user 2, then list names. Say both prints.
