+# 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!
