Awesome The Top 40 Free Ajax & Javascript Code for Web Designers

Ajax has becoming very popular recently, but most designers seem to rehash the same script over and over (you’ll see it in a lot of WordPress Themes and Plugins). Perhaps we aren’t using ajax technology to its full potential, myself included. The list below is made up of the best FREE scripts available, they are all of the highest quality and more or less easy to configure. Give them a try.
