debugging javascript

[Zbigniew Koziol]

Firebug is just unreplacable debugger of JavaScript. Unfortunately, it
does not run (yet) under version 3 of firefox, just only under version
2. It is worth however an efford and mess caused by installing an
additional older version of firefox. You will love it.

I did not even looked into your code - I am on vacation and using
computer of friend.

Firebug will list the exact line of code where an error occurrs. It
allows for interactive debugging and running the code, as well as
using break points and viewing values of variables at any stage of
code execution.
