Over the past years, development for the ClojureScript compiler has moved at a fast pace and its community is growing continuously. It's a fun community which I enjoyed to be a part of over the past months through my Google Summer of Code project. In this talk I will give an overview of the moving parts of the ClojureScript compiler, dive into some details about the compilation process itself with a hands-on example and will provide you with some pointers on how you could start contributing to the compiler.
