The first iteration occurs on the second item of the array, so the first parameter is the first item of the array, and the second is the second item of the array.You can use the reduce () method to perform an operation that evaluates the sum of all the values in the array, such as:var values = [1,2,3,4,5]; var sum = values.reduce (function (prev, cur, index, array) { return prev + cur; }); alert
