> How do people think JavaScript works?

Very slowly. Java, OCaml, or LuaJIT would be better examples here!

How many of the "GC is always slow" people would recognize those systems? Besides: V8 and JSC have pretty decent JITs nowadays. IME, performance of JIT systems has more to do with the structure of programs written in JS than with VM performance itself.

		Maybe I don't know what I'm doing, but I rarely get performance within an order of magnitude of single-threaded C from V8. In those other systems I usually do, unless you count Java's startup time.
