A Compiler Writing Playground

 "Create Your Own Compiler" is an interactive tutorial that step by step shows how to write your own simple compiler that transforms JavaScript into Lisp. Along with it, we take a look at what a compiler actually is and the state of the art that is Roslyn.

Compilers are important, but most people go day by day using their favorite programming language and tools without
thinking too much about them, ignoring what happens under the covers.
