Hello, please add a _collection.toMap(keySelector, [valueSelector]) function, so I can do this:

collection.toMap(x => x.key)

instead of this:

new Map(collection.map(x => [x.key, x]))

Please also add .toMap() to the groupBy() result so I can do this:

.groupBy(x => x.key).toMap(x => x.Key, x => x)

instead of this:

new Map(.groupBy(x => x.key).map((values, key): [string, T[]] => [key, values]).value())
