JavaScript

With with self hosted, everything we talked about the analyzer and the compiler and all that. It's all written in closure, right? And what was it like three or four years ago reader conditionals were added to the language. You know, you could do you could have little conditional branches where you can say like if this is compiled under closure, take the CLJ branch. If it's compiled under closure script,take the CLJS branch. So then using those two things together lets you effectively compile code from within the target JavaScript environment.
