Java uses multiple threads even for single threaded code, the JIT compiler has threads, the garbage collector has its own separate threads. I don't see why a JS implementation wouldn't be multi-threaded even if it is presenting a single threaded environment. Seems crazy to not know your application's performance profile before picking out the hardware to run it.
