# Get the Titles!
|
||||
|
||||
You are given an array of objects that represent books with an author and a title that looks like this:
|
||||
|
||||
```javascript
|
||||
const books = [
|
||||
{
|
||||
title: 'Book',
|
||||
author: 'Name'
|
||||
},
|
||||
{
|
||||
title: 'Book2',
|
||||
author: 'Name2'
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
your job is to write a function that takes the array and returns an array of titles:
|
||||
|
||||
```javascript
|
||||
getTheTitles(books) // ['Book','Book2']
|
||||
```
|
||||
|
||||
## Hints
|
||||
|
||||
- You should use a built-in javascript method to do most of the work for you!
