Timer js
Posted: Sun Oct 20, 2013 3:34 pm
Hey all, not sure where I needed to post this, but I come across this js timer, and was curious how it works, or what it even does; as I don't know much about timers or js 
I think one of our members here has either wrote it or worked with it before, but don't remember which one, as I have a billion tidbits of code snippets running around that I've gathered lmao
