## Description

<section id='description'>

In its simplest usage, `Model.find()` accepts a query document (a JSON object) as the first argument, then a callback. It returns an array of matches. It supports an extremely wide range of search options. Read more in the docs.

## Instructions

<section id='instructions'>

Modify the `findPeopleByName` function to find all the people having a given name, using `Model.find() -> [Person]`

Use the function argument `personName` as the search key.

      getUserInput => $.post(getUserInput('url') + '/_api/find-all-by-name', {name: 'r@nd0mN4m3', age: 24, favoriteFoods: ['pizza']}).then(data => {
        assert.isArray(data, 'the response should be an Array');
        assert.equal(data[0].name, 'r@nd0mN4m3', 'item.name is not what expected');
        assert.equal(data[0].__v, 0, 'The item should be not previously edited');
        }, xhr => { throw new Error(xhr.responseText); })
```
