 The fundamental feature of any data structure is, of course, the ability to not only store data, but to be able to retrieve that data on command. So, now that we've learned how to create an array, let's begin to think about how we can access that array's information.
 When we define a simple array as seen below, there are 3 items in it:

 For example, if we want to retrieve the <code>"a"</code> from <code>ourArray</code> and assign it to a variable, we can do so with the following code:
 
-```
+```js
 let ourVariable = ourArray[0];
 // ourVariable equals "a"
