Working with JavaScript Arrays

In this lab, you will be working with JavaScript arrays. Arrays are zero-indexed data collections with many built-in methods. These methods help you access and manipulate the values (elements) of an array.

You will declare an array and use built-in methods to access and add values to the array. Each check will ask you to output the current value of the array to the console.
