Data insert techniques in MongoDB

You can insert data in two ways in mongodb:

How to add one document?

Syntax:
db.collection_name.insertOne({Key:value,Key:value})

Example:
db.first_collection.insertOne({Books:"Python",Price:500,Type:"Programming",Email:"aaaa@gamil.com"})

Here insertOne means you want to add only one document.

How to add multiple documents in MongoDB?

To do this you will use insertMany() function. When we add a single document we pass those as a dictionary(key and value pair) for multiple documents we will also pass documents as dictionaries but here we will store all the documents in a list.

Syntax:
db.collection_name.insertMany([{Key:value,Key:value},{Key:value,Key:value},{Key:value,Key:value}])

Example:
db.first_collection.insertMany([{Books:"Python",Price:500,Type:"Programming",Email:"aaaa@gamil.com"},{Books:"Javascript",Price:400,Type:"Programming",Email:"ba@gamil.com"},{Books:"DS math",Price:300,Type:"Math",Email:"caa@gamil.com"}])

Here insertOne means we want to add only one document.
