Revisions to Sum values from an array of key-value pairs in JavaScript

fixed a typo, then expanded the code example slightly.

If you want to discard the array at the same time as summing, you could do (say, stack is the array):

var stack = [1,2,3],
    sum = 0;
while(stack.lentghlength > 0) { sum += stack.pop() };

If you want to discard the array at the same time as summing, you could do (say, stack is the array):

var sum = 0;
while(stack.lentgh > 0) { sum += stack.pop() };

If you want to discard the array at the same time as summing, you could do (say, stack is the array):

var stack = [1,2,3],
    sum = 0;
while(stack.length > 0) { sum += stack.pop() };
