From Overview of JavaScript I -- Basic Web Scripting Language CPS616 Technologies of the Information Age -- Spring Semester 99. by Geoffrey C. Fox (Tom Scavo)


Typically JavaScript is invoked from HTML and HTML text and JavaScript text are intertwined
If you need to make a dynamic page from C++ Perl or Java you must write the HTML from these languages
You can invoke applets from HTML but HTML and applet actions are not linked. In case of JavaScript HTML and JavaScript are closely linked
JavaScript is an example of an important concept -- the domain specific interpreter which we can expect to be of growing importance
  • Note Postscript is an interpreter for text layout; MATLAB an interpreter for Matrix arithmetic, Mathematica or Maple for Mathematics .....
Text ...................................................... Computer Language HTML---> JavaScript Java <----- C++
