Workshop: Building a Simple Compiler in JavaScript
NodeFest 2018
This is the set of slides and workshop materials for the compiler workshop I gave at NodeFest 2018.
“Compilers” are usually-mysterious things that a lot of us actually use and rely on from day to day, eg. the JavaScript V8 compiler, the TypeScript compiler, or the Clang+LLVM compilers. Digging into how these work can be satisfying (like sleuthing a good puzzle); but some of the ways we implement them can appear in other forms, such as when validating user input, transforming big structures, or when separating side-effects from business logic.
This workshop is comprised of a short talk that introduces the main parts of a compiler, followed by an at-your-own-pace tour through building a little one of your own. We’ll start with a simple language that compiles to JavaScript.
