SCALAJS - WEB WITHOUT PAIN OF JAVASCRIPT

on YouTube ↗31m

" summary

Scala.js compiles Scala to JavaScript so the same case classes & validations can run on client and server, enabling a hybrid insurance slider app that switches computation between browser and JVM. SBT offers fastOpt (1–5s) for rapid dev cycles and fullOpt + Closure (~100KB) for production; runtime is roughly within 50% of hand‑written JS in real use but can be slower in microbenchmarks. Integrations exist for jQuery, React and (old) Angular; debugging uses source maps but there is no runtime reflection and occasional need for JavaScript expertise.
