The Word frequency tool is based on an flash app created a while ago that ranks the most frequently used words that is pasted in the form.
It includes the ability to filter out words smaller than 4 characters and other commonly used words.
Since the slow demise and lack of support for flash on mobile devices, I wanted to get my hands dirty with some JS and jQuery and though what better way than to convert one of my AS3 projects. It wasn’t too hard making the switch as I found the languages pretty similar and jQuery made it very easy to use.
Anyways, enjoy the tool. Rip apart the code if you want or suggest some other features.
