It mimics Java, so your compiler compiles to a bytecode IR. The compiler as described by the book is a bare-bones recursive descent compiler that doesn't do any AST analysis. The compiler is for a toy language called Jack (fake Java) that was intentionally designed to be easy to write a compiler for. L(1) grammar I believe. They don't really talk about error handling or more complex compiler topics. No optimization methods are covered.

N2Tetris is like doing the 20% to get the 80% of every layer of abstraction. It really scopes down each project so you can cover every layer between logic gates and a high level language with built in OS APIs. I think it's a fantastic course but if you're looking to learn specifically about compilers I'm not sure if it'll meet your needs.
