Achievement Unlocked!

I am holding in my hot little hands a signed offer letter from Google. Assuming all the paperwork falls into place I'll be starting there on September 4 as a Senior Web Developer. I'm very excited about the opportunity. I'm not sure I can say what I'm going to be working on just yet, but don't let that stop you from guessing the answer.

Don't worry, on the side I'll continue working on jQuery Mobile and my other writing projects--with a new one to be announced soon, I hope.

JavaScript Interview Question 3: Largest Continuous Sum of an Array

Continuing the series on JavaScript Interview Questions, here's the next one: given an array of positive and negative integers, find the largest continuous sum.

This is pretty simple to do in JavaScript and uses the same algorithm that Arden describes in his original post:

function optimalSolution(arrIntegers) {
    var maxSum = 0,
        currentSum = 0,
        i = 0,
        arrIntegersLength = arrIntegers.length;
    
    if (arrIntegersLength === 0) {
        return;
    }
    
    for (i = 0; i < arrIntegersLength; i++) {
        currentSum = Math.max((currentSum+arrIntegers[i]), arrIntegers[i]);
        maxSum = Math.max(currentSum, maxSum);
    }
    return maxSum
}

Here I have optimized the loop but otherwise it's almost exactly the same as Arden's solution in Python.
