I've been working on a browser-based word game, naturally written in JavaScript, and have been encountering some interesting technical challenges along the way. I've written up my thought process here for others to learn from (note that most of this happened over the course of a month, or so). I've often found that while a final solution to a problem may be rather elegant and "make perfect sense" when looking at it - it's only through the result of much trial and error that the solution was arrived upon.

To start, in my game, the user is frequently re-arranging letters - causing the game to look up words in a dictionary to see if they are valid, or not.

I've taken multiple passes at implementing a solution to this problem, ranging all the way from "I don't care about performance, I just want it to work" all the way up to "thousands of people could be playing simultaneously, how do I scale?"
