10 years of Scala.js
summary
First commit lands February 5, 2013 and five weeks later introduces statically typed facades for JS interoperability drawn from TypeScript; the project adds dead‑code elimination, a custom optimizer and Google Closure Compiler integration, plus 2,000 cross‑platform tests and ~9,000 Scala.js‑specific tests. The 0.6.x line maintains compatibility for five years; since Scala.js 1.7.0 releases ship with zero known bugs per release. Ecosystem highlights: Laminar, Tyrian, Slinky, Scala.js React, Indigo; tooling includes ScalablyTyped + Vite plugin and faster linker, but onboarding and ECMAScript module minification still need work.
