MongoDB Insert

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

Smallest example: the smallest MongoDB Insert example you can type. Type it, run it, and say what you see. If you can do that from memory, you know MongoDB Insert.

From the example next to this theory — MongoDB Insert: find user 2, then list names.

Trap — only saying “MongoDB Insert” with no example. Fix that before you talk about advanced Node.js.

Viva — what is MongoDB Insert? Then show the smallest MongoDB Insert example you can type. Then name the trap.

Exam tip

What is MongoDB Insert? Show this: the smallest MongoDB Insert example you can type. Trap: only saying “MongoDB Insert” with no example.

Example

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