The language used isn't the interesting bit here...it's a physical exploit. That is bad ass...they're using the frequency of data writes to one sector to manipulate other unrelated sectors.
Think of it as running a magnet across the chip to wipe the bits...now...instead of a magnet I just start writing to one chip super fast to create that same field and manipulate stuff around it.
It's an awesome hack.

I'm not sure you understood the article. The vulnerability in question is hardware oriented: they only used JavaScript to demonstrate it.
Rowhammer could theoretically be exploited by almost any computer process. It doesn't matter what software/language/operating-system is used. It is a CPU security hole - which is something that can't be fixed without a major BIOs update. Assuming one is provided, and the user is savvy enough to install it.
For now, it has only been demonstrated locally.
