Netscape renames Livescript as Javascript and this is an interesting variant of Java which is fully interpreted -- use for overall customization of client
Use Java for detailed programming and JavaScript for overall integration of client interface and system
JavaScript: Interpreted by client and NOT compiled
Java: Compiled on Server before execution on client
  • Note both are reasonably "pure" C/C++ like languages and do NOT have useful sh/awk text and system enhancements of Perl(5)
JavaScript: Object based -- no classes or inheritance -- built in extensible objects
Java: Object-oriented. Programs consist of object classes with inheritance
