The output is pretty slim, it's one of the reasons I prefer using haxe over TypeScript when targeting the web – haxe has better dead-code-elimination so output js tends to be smaller and include a greater level of optimisation – check out this example to see what I mean https://try.haxe.org/#4f46D

True. I don't think the output will be particularly pretty, and it does assume the presence of its own stdlib. But hopefully it's still fun to see how exactly they do things under the hood.
