Almost all major operating system developers (IBM, Microsoft, and others) have added Java(3)compilers as part oftheir product offerings.
The Java virtual machine includes an optional just-in-time compiler that(4)dynamically compiles bytecode into executable code as an alternative to(5)interpreting one bytecode instruction at a time. In many(6)cases, the dynamic JIT compilation is faster than the virtual machine interpretation.

JavaScript, which originated at Netscape, is interpreted at a higher level, is easier to learn than Java, but(8)lacks some of the portability of Java and the speed of bytecode. Because Java applets will run on almost any operating system without(8)requiring recompilation and because Java has no operating system-unique extensions or variations, Java is generally regarded as the most strategic(10)language in which to develop applications for the Web.
