PyPy.js: What? How? Why? by Ryan Kelly (PyCon 2015 Must-See Talk: 5/6)

Part five of six in our PyCon 2015 Must-See Series, a weekly highlight of talks our staff enjoyed at PyCon.

From Ryan Kelly's talk I learned that it is actually possible, today, to run Python in a web browser (not something that interprets Python-like syntax and translates it into JavaScript, but an actual Python interpreter!). PyPy.js combines two technologies, PyPy (the Python interpreter written in Python) and Emscripten (an LLVM-to-JavaScript converter, typically used for getting games running in the browser), to run PyPy in the browser. This talk is a must-see for anyone who's longed before to write client-side Python instead of JavaScript for a web app. While realistically being able to do this in production may still be a ways off, at least in part due to the multiple megabytes of JavaScript one needs to download to get it working, I enjoyed the view Ryan's talk provided into the internals of this project. PyPy itself is always fascinating, and this talk made it even more so.
