    Project mention: Show HN: Programming Google Flutter with Clojure | | 2022-12-01
  • Laminar

    Simple, expressive, and safe UI library for Scala.js (by raquo)

    Project mention: 10 Years of Scala.js | | 2023-02-05

    Scala.js core itself, which I maintain, does not need much innovation. We support all of Scala, and interact with any JavaScript library. That's what the core promises.

    If you want to compare to Scala 3, it's worth pointing out that you can use Scala.js with any Scala version >= 2.12.2. In particular, you can use it with Scala 3 and benefit from all its innovations. ;)

    Innovation comes mainly from libraries, notably UI libraries. Laminar ( is a great example.

    In terms of roadmap, we are mostly working on "boring" stuff: improving performance (of the generated code, and of the linker), fixing bugs when they get reported, etc.

    Perhaps, when Wasm gets more features for deeper interoperability with JavaScript (manipulating objects notably), we will take another look at targeting Wasm. People usually expect all languages to target Wasm now, "because it's fast". Truth is, it's fast for languages with linear memory. There is no evidence yet that it will be fast for memory-managed languages with objects and virtual dispatch.
