What are the different data types in MongoDB?

MongoDB supports several data types including String, Number, Boolean, Array, Object, and more. Would you like details on each?

Yes, please explain each data type.

Sure!

1. String: Used for text.
2. Number: Can be integer or floating point.
3. Boolean: Represents true or false.
4. Array: A list of values.
5. Object: A document containing key-value pairs.
6. Null: Represents a null value.

What is the difference between an Object and an Array?

An Object is a set of key-value pairs, while an Array is an ordered list of values. Objects are used for structured data, whereas Arrays are used for lists.

Can you give an example of how to use these data types in a MongoDB document?

Certainly! A MongoDB document might look like this:

{ 
  "name": "John", 
  "age": 30, 
  "isStudent": false, 
  "courses": ["Math", "Science"], 
  "address": {"city": "New York", "zip": "10001"}, 
  "graduationDate": null 
} 
``` This document uses String, Number, Boolean, Array, Object, and Null.
