Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
Uses [initialValue] as the initial value, then iterates through the elements and updates the value with each element using the [combine] function, as if by:
var value = initialValue; for (E element in this) { value = combine(value, element); } return value;
Example of calculating the sum of an iterable:
iterable.fold(0, (prev, element) => prev + element);
