Offtopic, but I hate the usage of the word "transpiler" and I hate how popular it got.

First of all the word "compiler" is perfectly adequate to convey the meaning of a "transpiler", meaning a computer program whose purpose is to translate code from one programming language into another. The usage of the word "transpiler" only happened because of languages like CoffeeScript, as a word was needed to express that CoffeeScript is just as broken as Javascript, but with syntax changed for no good reason.

But more importantly, many compilers that target Javascript, such as Scala.js, ClojureScript, GHCJS, Dart, are very much not like CoffeeScript, meaning that we are talking about languages with different type and module systems, with big standard libraries, that treat Javascript as bytecode and that need to be compressed with Google Closure to be viable. If you're missing the source-maps, the end result will be much harder to understand than Java or .NET bytecode. Therefore the usage of the word "transpiler" in this context is not only annoying, but incorrect as well.
