Module "xform/mapcat-indexed"

mapcatIndexed

• mapcatIndexed<A, B>(fn: Fn2<number, A, Iterable<B> | null | undefined>, offset?: undefined | number): Transducer<A, B>
• mapcatIndexed<A, B>(fn: Fn2<number, A, Iterable<B> | null | undefined>, src: Iterable<A>): IterableIterator<B>
• mapcatIndexed<A, B>(fn: Fn2<number, A, Iterable<B> | null | undefined>, offset: number, src: Iterable<A>): IterableIterator<B>

• Transducer. Similar to {@link (mapcat:1)}, but given fn takes two arguments: index and value to transform.

  remarks

  An optional start index offset can be provided (default 0). Also see {@link (mapIndexed:1)}.
