My Javascript Tip (or prointer) of the day.
Are you using alert('my message'); to debug your javascript?
This little tool is a must have and will change your javascript coding forever.
Add tracing to your javascript functions with jsTrace. What a great little util. I had it up and running < 5 minutes, and I can't image I'll write another line of javascript without using this tool.
It consists of two JS files, that you simply remove before you deploy.
