Function flatMapDeep

  • flatMapDeep<T>(collection): T[]

  • This method is like _.flatMap except that it recursively flattens the mapped results.

    Type Parameters

    • T

    Parameters

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

      The collection to iterate over.

    Returns T[]

    Returns the new flattened array.

    Since

    4.7.0

    Example

    function duplicate(n) {
      return [[[n, n]]];
    }

    _.flatMapDeep([1, 2], duplicate);
    // => [1, 1, 2, 2]
