Really you should be starting with bash, thats how you know why these other languages exist. My rule of thumb used to be if I have more than one "if" in a shell script then its going to python... But now its any ifs or variables

Edit: now that I read the readme I think the title should have been "show hn: I made a web framework in bash" this is pretty neat, I still wouldnt use it, but its cool as hell.
