I may be missing something, but it seems like the purpose of this library is to solve the problem that if you run too much code in javascript in the browser at any given time you can hog the application thread long enough that it makes the user interface lag. So you can break up your operations into chunks that will be executed in order. This library will help you run functions in order and not all at once without having to use callbacks and setTimeout(function(){...}, 1).
