arrayReduce

Iterates over every entry of the array and calls the closure to work on the elements of the array. This function will reduce the array to a single value and will return the value.

arrayReduce(array, function(result, item [,index, array]){} [, initialValue]) → returns any

Member Function Syntax

someArray.reduce(function(result, item [,index, array]){} [, initialValue])
