Inserting a Document into a MongoDB Collection

To insert a document in MongoDB, you can use the insert() method on a collection. The method takes a single argument, which is the document to insert. Here's an example of how to insert a document with multiple key-value pairs:

db.collectionName.insert({
    "key1": "value1",
    "key2": "value2",
    "key3": "value3",
    "key4": "value4"
})

In this example, db is the name of the current database, collectionName is the name of the collection in which you want to insert the document, and insert is the MongoDB command to insert a document in the collection. Each key-value pair within the document is enclosed in curly braces {}.

Additionally, you can use insertOne or insertMany methods, depending on whether you want to insert a single document or multiple documents at once.

db.collectionName.insertOne({
    "key1": "value1",
    "key2": "value2",
    "key3": "value3",
    "key4": "value4"
})

db.collectionName.insertMany([    { "key1": "value1", "key2": "value2" },    { "key3": "value3", "key4": "value4" }])

This will insert the documents in the collection.
