To put in my $0.02 -

I'd argue that both CS and JS are very readable. Since we are entering a point that about 1/4 of JS libraries are written in CS (my estimate, not actual statistic), knowing both is becoming essential.

Because of Rails, I have transitioned to CS myself. However the times when I need to read/edit JS it is always easy to drop down to it. I am not geting into any religious wars but I will say this in favor of CS:

Code written in it is about 1/3 shorter than corresponding JS code. Since all code has bugs, less code means less bugs.
