tslox

This is a TypeScript implementation of the Lox language tree-walking interpreter from the book Crafting Interpreters by Bob Nystrom.

I wrote this project while following Part II of the book, which covers the implementation of the Lox interpreter in Java. I picked TypeScript because I have a good knowledge of it and I wanted to focus more on the interpreter itself rather than learning Java.
