Module iterable/reduce

reduce

• reduce<T, R>(reducer: IterableReduceFunc<T, R>, initialValue: R, iterable: Iterable<T>): R
• reduce<T, R>(reducer: IterableReduceFunc<T, R>, initialValue: R): (iterable: Iterable<T>) => R
• reduce<T, R>(reducer: IterableReduceFunc<T, R>): CurriedFunction2<R, Iterable<T>, R>

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

  example

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

  Type parameters

  • T

  • R

  Parameters

  • reducer: IterableReduceFunc<T, R>

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

  • initialValue: R

    The initial value.

  • iterable: Iterable<T>

    The iterable target to iterate over.

  Returns R

  The final, accumulated value.
