An array is indexed by an integer (myarray[0]) while a hash is indexed by any 
Ruby object (myhash["drinks"]).

In Ruby 1.9 Hashes are also ordered (an important difference between a typical 
hash and an array present in Ruby 1.8).

If you need to access the entries based on a numeric index Arrays are valid 
for you. If not, Hashes are great.
