different views, explaining that bytecode is definitely slower than running at full speed, and sacrificing performance to cross-platform benefits is worth it?However, the JVM has an option to translate the most frequently used bytecode into machine code and save it, a process known as instant compilation. This is really effective, and the Microsoft. NET platform also uses virtual machines.The now-in-time compilers have been pretty good, even as competitors of traditional compilers, and in some
