The powerful Helma application server brings new powers to the JavaScript language. We'll show you how to use Helma to build a simple RSS reader.

JavaScript began as a dynamic scripting language for the browser. The JavaScript language is prototype-based with syntax reminiscent of C or Java. Because JavaScript includes higher order closures and functions, it is referred to as a functional language, as are the languages Lisp and OCaml. JavaScript became popular because of its use in browsers, but it eventually gained a bad reputation for language and library incompatibility. Thanks to standardization through the vendor-neutral ECMAScript standard, as well as new browser libraries such as Yahoo YUI, Mochikit, or Mootools, the picture is starting to change, and Java-Script is gradually becoming a mature
programming environment.
