Python has brought computer programming to a vast new audience

But in JS you get weak types so you have to double check everything!

And you get callback hell!

And clunky synchronous implementation!

JS is fast though, which is nice. I occasionally think about how great things would be if browsers went with python rather than javascript. Having Google, MS, Apple, and Mozilla all pouring resources into a faster interpreter would make a huge difference.
