Module array/groupBy

groupBy

• groupBy<T>(fns: ArrPred<T>[], list: ArrayLike<T>): T[][]
• groupBy<T>(fns: ArrPred<T>[]): (list: ArrayLike<T>) => T[][]

• Creates an array of arrays generated from the results of running each element of list thru each fn. The corresponding value of each index is an array of elements satisfies to function with that index, and the last array is elements with no satisfied function

  example

  groupBy([isPositive, isZero, isNegative], [0, -3, 2, 'str', 4, -1]);//=> [[2,4], [0], [-3, -1], ['str']]

  Type parameters

  • T

  Parameters

  • fns: ArrPred<T>[]

    The functions to check values in a list.

  • list: ArrayLike<T>

    The list to iterate over.

  Returns T[][]

  Returns the composed array.
