INSERT ARRAY OF DATAS IN DOCUMENT

To insert an array of data into a document in MongoDB, you can use the insertOne() method with an object that contains an array field. The array field can then contain any number of elements, including strings, numbers, objects, or other arrays.

Here's an example query that inserts a document with an array of hobbies into a collection called "students":

db.students.insertOne({"_id":2,"name":"Sara","hobbies":["Dancing","Drawing","Singing"]});  

In this example, we're inserting a document with an _id of 2, a name of "Sara", and an array of hobbies that includes "Dancing", "Drawing", and "Singing".

If you want to insert multiple documents with arrays, you can use the insertMany() method instead of insertOne(), and pass an array of objects to the method.

You can now insert an array of data into a document in MongoDB using the insertOne() method.
