Function flatMap

  • flatMap<T>(collection): T[]

  • Creates an array of flattened values by running each element in collection through iteratee and concating its result to the other mapped values. The iteratee is invoked with three arguments: (value, index|key, collection).

    Type Parameters

    • T

    Parameters

    • collection:
          | undefined
          | null
          | Dictionary<Many<T>>
          | NumericDictionary<Many<T>>

      The collection to iterate over.

    Returns T[]

    Returns the new flattened array.
