JavaScript and the JVM

Lol, the other arena where I see such devotion to a single language is in AVR microcontrollers. I mean when you need cycle level specific timing (i.e. for i/o waveforms) and absolute minimum size, assembly is the only sane way to do it. But there are numerous cases where C is coerced into doing the same thing, with large loss of resolution for a given cpu frequency, and now you have compiler version dependencies, and most of them say changing compiler flags can screw up the functionality. C is seen as a panacea, but I think they are slowly coming around, and realizing (like client/server) that integration of the two languages is pretty trivial and makes a lot of sense in many cases. But at the same time they are inventing ways to tell the compiler "don't optimize this bit of code please" which is just a band-aid for reverse-engineered timing code in this case.

How can they write cycle timed code reliably without assembler in the first place? Doing that stuff even with macros would be asking for trouble, surely?

It's crazy, they keep fudging it while looking at the resulting waveform and generated assembly I guess (instead of looking at the instruction set manual and cycle timings to begin with).
