📥 MongoDB Insert Documents

In MongoDB, you insert data as documents into collections. A document is a JSON-like structure that holds data as key-value pairs.

🔹 Insert One Document

Use insertOne() to insert a single document into a collection.

db.students.insertOne({
  name: "Rahul Kumar",
  age: 22,
  course: "B.Tech"
});
  

🔹 Insert Multiple Documents

Use insertMany() to insert multiple documents at once.

db.students.insertMany([
  { name: "Aisha", age: 21, course: "B.Sc" },
  { name: "Varun", age: 23, course: "MBA" }
]);
  

🧾 Note on Document Structure

Each document will automatically be assigned a unique _id field by MongoDB unless you specify one.
