3. What does ORM stand for? Which ORM do we use when interacting with MongoDB

ORM is object relational mapping. It is a way of organizing and connecting information to each other for your api server. 

4. Which two HTTP request types include a body?

The Post and Put request contain a body, because you are changing or adding info. The other two just see or delete info.

5. In a/an _______ coding model, when you call a function, it returns only when the action has finished and stops your program for the time the action takes. Likewise in a/an _______ coding model, multiple things are allowed to happen at one time. When you perform an action, your program continues to run. Fill in the blanks.

The first blank is an await coding model, while the other is an async coding model. 

6. Fill in the missing piece of this snippet of code.

import ______ from "_______"
let Schema = ________.Schema;
