Describes building Boa, a JavaScript engine implemented in Rust, covering parsing, execution, and interpreter/runtime details driven by the ECMAScript spec. Covers engineering and community lessons from leading an open-source engine project—growing contributors and maintaining a runtime—and finishes by describing how the work fed into contributions to V8 via a Rust-based implementation of Temporal.
