wordsolver.js
I was playing around with unscrambling words recently, and decided to implement a solver in JavaScript. I called it wordsolver.js.
Demo
There is a wordsolver demo on my site. Try typing in URESMTA or something to see all the words that get unscrambled.
Code
All code can be found in the wordsolver repository on github. In particular, here is the file that does all the heavy lifting. It is all available under the MIT license.
How does it perform?
Smoother than I expected it to. The load time for the dictionaries can be pretty slow (they are anywhere from 1.7MB to 2.6MB depending on the dictionary), but once it loads, it finds words pretty fast and tries to cache results. Warning: it will probably crash an iPhone while trying to load the dictionary array into memory
