It is very widely deployed and will work on almost all client devices.
That dosen't really say much about the language itself though, which I think was what was being called 'beautiful' (as opposed the ecosystem).
Besides, couldn't the same argument be made about C? Sure I know a lot of people 'like' C, but I don't think I've ever heard of it being referred to as 'beautiful'...
C's beauty is in its simplicity.
C isn't really beautiful anymore but to somebody used to program in assembly it properly is beautiful.
Nice expressivity, mostly functional, fun to use, etc.
It has closures, I don't really know if it has anything else in common with a functional language...
