The strange thing about this is that I've found that both make great additions to my toolbox, and when making my language choice I don't pick JS or Ruby so much as I pick Node or Rails/Sinatra and I don't do the same things with each stack. I've long gotten past worrying too much about languages Ruby and JS are so close to each other that switching between the two is a frictionless process.
