Title: about_array.rb

*Created an empty array with a size of
zero
*<< sends element to array without
calling its element.
*when you go backwards in array it
doesn't begin at element 0
*slicing array cuts off at elements in
this case 4 is at end of slice but not 5
*how many dots in range specify where
class range ends
*you can slice with ranges
*pop/push add and subtract from end of
array
*unshift add to beginning of array
