Has Javascript succeeded to be a language that could easily be run everywhere compared to others?

Question

Javascript:

• can be run on web browsers with sproutcore/cappuccino.
• can be run on web server with node.js/express.
• can be run on mobile phones with appcelerator/phonegap.
• can be run on the terminal as scripts.

Of course javascript will grows stronger on the latter three areas by time.

I read somewhere someone said something like:

"What coders want is very simple: One language, everywhere".

Has Javascript succeeded to be a language that could be run everywhere compared to others?

I cannot name another language that could.

Answer 1

Well, there's always C. I've heard that runs everywhere.
