const { splitOn } = AsyncTransformer;

Returns an AsyncTransformer that collects the received elements into a collector that will be returned as output every time the input matches the given sepElem value.

Parameters

sepElem: T
  • a potentially async predicate function taking an element
optional
options: { eq?: Eq<T> | undefined; negate?: boolean | undefined; collector?: AsyncReducer.Accept<T, R> | undefined; } = [UNSUPPORTED]
  • (optional) object specifying the following properties
  • eq - (default: Eq.objectIs) the equality testing function
  • negate: (default: false) when true will negate the given predicate
  • collector: (default: Reducer.toArray()) an AsyncReducer that can accept multiple values and reduce them into a single value of type R.
