// Since ES6 Map()'s' retain their order of insertion, it can sometimes be useful to get the last item or value inserted:

export const getLastItemInMap = map => Array.from(map)[map.size-1]
export const getLastKeyInMap = map => Array.from(map)[map.size-1][0]
export const getLastValueInMap = map => Array.from(map)[map.size-1][1]

// Obviously getLastKey and getLastValue can reuse getLastItem, but for maximum portability I opted for verbosity.
