I do sometimes go back and stare at this wonder I crafted once: s=>s[0]+/.( .|z)|...s.s?|T..|M[i-t]+|[AFINOUW][^o]v?|./.exec(s)[0].slice(-1).toUpperCase()

I do sometimes go back and stare at this wonder I crafted once: s=>s[0]+/.*( .|z)|...s.s?|T..|M[i-t]+|[AFINOUW][^o]v?|.*/.exec(s)[0].slice(-1).toUpperCase() It does something pretty useful, that has surely been written many times over. But unlikely ever as succinctly as this. :)
