As a Programmer I have to deal with a number of programming languages to write code, and one language that repeatedly appears is JavaScript. JavaScript is one of the weirder languages - similar to PHP in weirdness - which makes it an interesting experience to say the least. Most of the time you're at the whim of a grey box compiler, due to the massive variance of Browsers and Devices that the users use. So in order to best approach reality, I have to figure out which APIs are available at any point in time, and also run performance benchmarks...
