Is there a particular reason why Amazon chose JavaScript? I'm seeing more and more PAAS services going nodejs first/only and am wondering if there's an underlying reason.
what is even more interesting is that you felt it worked nicely for expressing event handlers. Can you talk a bit more about that - very interesting to see why not something like python or ruby. I know that nodejs is a callback-oriented framework... was it the fact that you can test locally on nodejs consistently versus what would be the expected output on Lambda ?
