codecrafters (YC S22, http://codecrafters.io) has a new module called "Building Your Own Interpreter" that works its way through this book. It's great because you work in small chunks, each of which has unit tests to tell you if you got, e.g. scanning string literals correct.

Currently free while the module is in beta. I spent today working through all of the lexer exercises in Rust (I'm currently learning it), and had a lot of fun.
