Push Targets

Push targets are just observers.

toArray

toArray() => Observer

Returns an observer that saves all items into an array. The observer has the values property to access this array.

toConsumer

toConsumer(consumer, finalizer) => Observer

Returns an observer that passes items into the consumer. On end-of-sequence or error the finalizer will be called with the error (if any, or undefined) and items count.

toNull

toNull() => Observer

Returns an observer that does nothing.

toValue

toValue() => Observer

Returns an observer that saves the first item into the own value property. There's also hasValue property to check if there was an item at all.
