Function expand

expand<TSource>(selector): MonoTypeOperatorAsyncFunction<TSource>
Expands (breadth first) the async-iterable sequence by recursively applying a selector function to generate more sequences at each recursion level.
Type Parameters
- TSource
  
  Source sequence element type.
Parameters
- selector: ((value, signal?) => AsyncIterable<TSource> | Promise<AsyncIterable<TSource>>)
  
  Selector function to retrieve the next sequence to expand.
  - - (value, signal?): AsyncIterable<TSource> | Promise<AsyncIterable<TSource>>
    - Parameters
      
      value: TSource
      
      Optional signal: AbortSignal
      
      Returns AsyncIterable<TSource> | Promise<AsyncIterable<TSource>>
Returns MonoTypeOperatorAsyncFunction<TSource>
An operator which returns a sequence with results from the recursive expansion of the source sequence.
