A hash ( associative array or a dictionary) is an array holding a collection of data
# you can index it using text strings as well as numbers.
# To create a hash, you use curly braces, { and }, not square braces ([]) as with arrays.
money = {"Dan" => "$1,000,000", "Mike" => "$500,000"}
# "Dan" is a hash key
# "$1,000,000" is the value.
# The => operator separates the keys from the values.
