Topic: Question on the Bang (!)

I've been trying to find out what this does in Ruby. I know it as a Not operator but recently I've seen it used in front of an object to return a boolean.

any help is appreciated.

Ruby has a simple definition of truth. Any value that is not nil or the constant false is true.

Does this answer the question?
