What is the difference between the normal and the min qoodoo js file?
Which file should I use to write some js for my web browser?
They have exactly the same functionality. However, javascript is often minfied to reduce the amount of code that is transferred from your server to your client's browser over the wire. For debugging, the normal file may suit you better. For production, the minified file (min qoodoo js) will be better because page loads will be quicker.
