Has anyone used Scala.js? It looks like version 1.0.0 was just released.
After 7 years of development, including 5 years of stability within the 0.6.x series, we are finally ready to present Scala.js 1.0.0. Quoting Antoine de Saint-Exupéry,
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.
Scala.js 1.0.0 is the culmination of our efforts to simplify, specify, and future-proof all aspects of Scala.js, from the language semantics to the internal APIs, so that there is nothing left to take away.
