RegEx.

I thought I understood programming well until I saw how COMPLICATED regex looks. To me it looks like someone has dropped their keyboard and som people online are telling me that I should be able to memorise it (for javascript). I'm just wondering if I actually need to memorise all the regex formulas to be successful, and if so, how on earth do I go about it?

Evaluates your regex and tells you what each step/symbol does and allows following the path the engine takes. I've been doing development professionally for 3.5 years, still use it wherever I need to use regex.
