JavaScript
functional programming

Most monad tutorials are long, confusing, and ineffective. I cannot promise this one will be more clear, more interesting, or even more effective, but I can at least promise to make it brisk. You have nothing to lose by reading it.

Presently, it isn't possible to change the motivation more than once per page load. On the second change, we throw an exception:

Get rid of that stupid single-var-declaration rule, once and for all

I don't like the single-var rule.

It annoys me for several reasons.

* Three's texture loader doesn't support onProgress events, because it uses image tags under the hood.

* A simple workaround is to AJAX the file into the cache with a FileLoader, then extract that into a
