In some cases, we use JavaScript as an alternative to Java where the "rapid prototyping" of a fully scripted language is helpful
-
We expect somebody to develop a fully interpreted Java and/or to extend JavaScript to support more built-in objects (e.g., networking, images)
-
Think of JavaScript as either active text (HTML) or a focused language!

JavaScript can be thought of as Java with the AWT (Abstract Windowing Toolkit) replaced by Netscape Client
-
JavaScript is a domain-specific interpreter for web documents
-
E.g., PostScript is a domain-specific interpreter for text layout, MATLAB is an interpreter for matrix manipulation, Mathematica is domain-specific for mathematics applications, etc.
