The Java Mafia and all their henchmen say that you can port them to other
platforms. False advertising?

If the browser has an interpreter for the JavaScript, then what do you call
the interpreter? Would it not make sense to call it a Java Interpreter?
Hence the relationship I see between JavaScript and Java, just like the
relationship between a Basic Program and a Basic Interpreter. The only
difference in the case of the browser is that the interpreter is compiled
into the browser program. A Basic Interpreter, on the other hand, is a
separate program, but such could probably be compiled and united into another
program in case anyone wanted to do such a thing. I am interested in
knowing if such has already been done.

This is like saying that if a machine has a micro-processor, then it can run
machine language programs designed for it, or that it could run any
higher-level programming language program provided the program is properly
written for it, and it is running an interpreter properly designed for it, or
a facility for running a program compiled specifically for use on said machine.
Hence the relationship between the scripting language and whatever the
facility that handles it. The name of the scripting language and the name of
the facility that handles it may be similar or different. Anyway, it doesn't
matter; however, the relationship between the two is clear.
