Why are UniDriverList.map and UniDriverList.filter not consistent in return value

[hepiyellow]

Current API

map returns an array while filter returns a UniDriverList.

export type UniDriverList<T = any> = {
	get: (idx: number) => UniDriver<T>,
	text: () => Promise<string[]>,
	count: () => Promise<number>,
	map: <T>(mapFn: MapFn<T>) => Promise<T[]>,
	filter: (predicate: PredicateFn) => UniDriverList
};

##Suggestion 1

Either go with Array of List

##Suggestion 2

Expose toArray. And then the consumer can use the Array's map, filter, find.

Because map works from A -> B and filter is from A -> A..
