  1. What do arrays allow us to do?
    A. The Array object lets you store multiple values in a single variable. It stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

  2. What index should you use in order to access the first element in an array?
    A. 0

    Store several variables of similar types.

  2. What index should you use in order to access the first element in an array?
    Index to zero.
    An array with 5 elements will be array[0], array[1], array[2], array[3], array[4], array[5]

What do arrays allow us to do?
Store multiple values inside a single variable.
(Example: var princessBubblegum = ["pink", "princess", "long hair"];
What index should you use in order to access the fist element in an array?
0 (An array with 3 elements will go pink[0] princess[1] long hair[2])

1: Arrays allow you to use multiple variables within the same type. Objects with the same data type.
2: You would use index 0 because all starting Arrays have the index 0 in most programming languages.
