What is the job market really like for Ruby and Python developers as opposed to that of JavaScript developers?

I have seen the graphs and numbers, but I'd like to know what it looks like from the perspective of a professional Ruby or Python developer who is actively employed and works with the supply and demand on a daily basis.

Please, do not feel the need to point out that JavaScript is quite a bit different than Ruby and Python. I am not asking how the languages relate, only how the job markets compare.
