What value does this provide over simply Googling or DDG'ing "array.map mdn"? It's shorter and the first result for me is (unsurprisingly) MDN on both, and I don't have to run my searches through an unknown third party.
DDG also has !bangs for this specific purpose and !mdn does, as expected, lead you to MDN.
