 | ||
|  | # --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--
 | ||
|  | 
 | ||
|  | Modify the `removeById` function to delete one person by the person's `_id`. You should use one of the methods `findByIdAndRemove()` or `findOneAndRemove()`. | ||
|  | 
 | ||
|  | # --hints--
 | ||
|  | 
 | ||
|  | Deleting an item should succeed | ||
|  | 
 | ||
|  | ```js | ||
|  | (getUserInput) => | ||
|  |   $.post(getUserInput('url') + '/_api/remove-one-person', { | ||
|  |     name: 'Jason Bourne', | ||
|  |     age: 36, | ||
|  |     favoriteFoods: ['apples'] | ||
|  |   }).then( | ||
|  |     (data) => { | ||
|  |       assert.equal(data.name, 'Jason Bourne', 'item.name is not what expected'); | ||
|  |       assert.equal(data.age, 36, 'item.age is not what expected'); | ||
|  |       assert.deepEqual( | ||
|  |         data.favoriteFoods, | ||
|  |         ['apples'], | ||
|  |         'item.favoriteFoods is not what expected' | ||
|  |       ); | ||
|  |       assert.equal(data.__v, 0); | ||
|  |       assert.equal(data.count, 0, 'the db items count is not what expected'); | ||
|  |     }, | ||
|  |     (xhr) => { | ||
|  |       throw new Error(xhr.responseText); | ||
|  |     } | ||
|  |   ); | ||
|  | ``` | ||
