## Description
|
|
|
|
<section id='description'>
|
|
|
|
`findByIdAndRemove` and `findOneAndRemove` are like the previous update methods. They pass the removed document to the db. As usual, use the function argument `personId` as the search key.

## Instructions
|
|
|
|
<section id='instructions'>
|
|
|
|
Modify the `removeById` function to delete one person by the person's `_id`. You should use one of the methods `findByIdAndRemove()` or `findOneAndRemove()`.
