Two months ago I blogged about how to be a Rockstar developer, and demonstrated it with a Rockstar interpreter called Maiden written in Rust. Now, normally Rust is considered a systems programming language (it even says so on the Rust homepage), and the command-line nature of Maiden aligned well with that. Except that Rust is slowly becoming more than that. Between “are we web yet?” and more recently WebAssembly support, Rust can be used for an ever-increasingly wider selection of projects.
TL;DR: there’s a browser version of Maiden now.
