A byte code compiler translates a complex high-level language like Lisp into a very simple language that can be interpreted by a very fast byte code interpreter, or virtual machine. Writing even a naive a bytecode interpreter and a bunch of programs for it makes you think about how things that you usually take for granted actually operate under the hood. Writing a new interpreter was also a good opportunity for me to learn Rust while writing a non-trivial project. Intro. In its own bytecode. Then I've got to write the compiler. This latter approach is similar to how the JVM executes bytecode. An introduction to Python bytecode. Direct interpreters tend to be slow, though.
