- In order to reduce the barrier to entry of the Cocoon flow layer for Java programmers that haven't done much with JavaScript I thought I'd give an overview of some of the similarities and differences between JavaScript (specifically Rhino - [http://www.mozilla.org/rhino]) and Java.

- I also encourage you to play around with the Cocoon Flow debugger ([http://xml.apache.org/cocoon/howto/howto-flow-debugger.html]), as it contains an interactive environment where you can type in JavaScript code and see the results.

+ !!Type of Variables
- JavaScript has two types of variables: global variables and local variables. Local variables are only visible in the function in which they are declared. However, they are also visible to other functions defined in the same scope. Inside a function definition local variables are identified by the "var" keyword:
