Seeing news such as this:
https://kotlinlang.org/docs/js-overview.html<p>Got me wondered.<p>We have gone long way since ActiveX,
Flash and closed web standards.<p>Can a commercially backed language (swift, Kotlin) can become dominant again?
The Go programming language is pretty much backed by Google. It really did not have a life outside of google AFAIK, when it burst onto the scene. It's now become the de-facto systems programming language. C is pretty much not used at the majority of places that need a lower-level statically typed, compiled language that needs no installed runtime; Go is now filling that use-case in a large majority of situations.
Java was created by Sun Microsystems.<p>SQL was created by IBM.<p>C# was created by Microsoft.<p>I don't know if your question was intended to mean "commercially successful" or if by commercially-backed you may have meant "closed source".
