So i've been developing a small app for myself (might release the code later) and i've been trying to test some Javascript. Yet i was always getting funny errors. Like the object doesn't exist, etc. Even though i have just created it. Anyway this morning, fresh pair of eyes i remembered Caching. Oh yes. Remember folks when testing Js (or CSS for that matter) to either hit `CTRl` and `R` for a fresh refresh or just set your browser to check for `newer version` on every visit.
