Module array/adjust

adjust

• adjust<T>(fn: Endo1<T>, index: number, list: ArrayLike<T>): T[]
• adjust<T>(fn: Endo1<T>, index: number): (list: ArrayLike<T>) => T[]
• adjust<T>(fn: Endo1<T>): CurriedFunction2<number, ArrayLike<T>, T[]>

• Applies a function to the value at the given index of an array, returning a new copy of the array with the element at the given index replaced with the result of the function application.

  example

   adjust(add(10), 1, [1, 2, 3]);     //=> [1, 12, 3]
   adjust(add(10))(1)([1, 2, 3]);     //=> [1, 12, 3]
  

  Type parameters

  • T

  Parameters

  • fn: Endo1<T>

    The function to apply.

  • index: number

  • list: ArrayLike<T>

    An array whose value at the supplied index will be replaced.

  Returns T[]

  A copy of the supplied array with the element at index idx replaced with the value returned by applying fn to the existing element.

• Applies a function to the value at the given index of an array, returning a new copy of the array with the element at the given index replaced with the result of the function application.

  example

   adjust(add(10), 1, [1, 2, 3]);     //=> [1, 12, 3]
   adjust(add(10))(1)([1, 2, 3]);     //=> [1, 12, 3]
