I love the (unintentional?) pun of using #pop to "kill" the array member :D

An even plus an odd integer will always return odd.

Just think of it. A pencil and a paper can help you.

This is a concise answer. but i thought it said, if one is even and the other is odd, they are in love. can someone explain how this code works
thanks!

This does not preseve whitespace.
" this is wrong" should arguably still include a leading space (as said by babakgh)
"this [space space space] is wrong" should arguably still have multiple spaces between 'this' and 'is'
EDIT: Aparently codewars also doesnt preserve multiple whitespace even in code blocks, but hopefully its clear what I mean

Fails with this " this is wrong "

Love it!

Wow, this is a clever way to use the send mehtod!!!

test this:

I say "go"

It won't work

it's a very neat and idiomatic code but as the pattern you capitalize is defined in split, it is not robust nor flexible at all.

Wow, this solution is so clever. :))

Then you displays a validation error until the user types without any errors.

I agree: "Ghost objects are given a random color attribute"

The color is an "attribute" of the object. So it should not change with each call to color.
