Good day!
Judging by the question and the provided code, you have no understanding of how asynchronous functions work in a node. In this answer , I already gave guidance on understanding asynchrony.
Now regarding the question.
If the code is written correctly, then the result is already stored in a variable, in this case, in the user
PS variable.
If you don't like callbacks, then use the ESNext goodies. mongodb native driver v3.0 ECMAScript Next CRUD
