Module array/reduce

reduce

• reduce<T, R>(fn: ReduceFunc<T, R>, acc: R, list: ArrayLike<T>): R
• reduce<T, R>(fn: ReduceFunc<T, R>, acc: R): (list: ArrayLike<T>) => R
• reduce<T, R>(fn: ReduceFunc<T, R>): CurriedFunction2<R, ArrayLike<T>, R>

• Returns a single item by iterating through the list, successively calling the iterable function and passing it an accumulator value and the current value from the array, and then passing the result to the next call.

  example

   var numbers = [1, 2, 3];
   var plus = (a, b) => a + b;
  
   reduce(plus, 10, numbers); //=> 16
  

  Type parameters

  • T

  • R

  Parameters

  • fn: ReduceFunc<T, R>

    The iterable function. Receives two values, the accumulator and the current element from the array.

  • acc: R

    The accumulator value.

  • list: ArrayLike<T>

  Returns R

  The final, accumulated value.

• Returns a single item by iterating through the list, successively calling the iterable function and passing it an accumulator value and the current value from the array, and then passing the result to the next call.
