Ruby array example

ruby-array-example.rb

array = [ :zero, :one, :two, :three, :four ]
print array.length # 5
print :four == array[4] # true — zero-indexed, so array[4] is the 5th item.
print array[5].nil? # true
print array[6].nil? #true

print [] # nil
print array[5, 0] # nil
print [] == array[5, 0] # true b/c both are nil

print nil # nil
print array[6, 0] # nil
print bil == array[5, 0] # true b/c both are nil

Ah, that makes sense. Thanks for pointing that out! Sorry I wasn't more of a concrete answer, but I'm glad you found it!
