puts FIRST_ARRAY[0] # => first constant value
puts SECOND_ARRAY[0] # => first
puts FIRST_ARRAY[1] # => second constant value
puts SECOND_ARRAY[1]

# So far so good

# But then remember these arrays don't contain constants...they just contain strings
puts FIRST_ARRAY.inspect # => ["first constant value", "second constant value"]

# If we were to directly access those constants we've defined we'll actually get different values than what's in the arrays. Not good :/
puts FIRST_CONSTANT # => first constant value REDEFINED!!!!

# As we can see freezing the arrays doesn't help since the arrays we're freezing are of strings
