I got 11 minutes and 14 seconds. Is that slow? The answer to my last solution was like this: function arraySum(i) { var total = 0 for(var x=0; x
function arraySum(i) { var total = 0 for(var x=0; x < i.length; x++) { if(typeof i[x] == 'object') { total += arraySum(i[x]) } else if(typeof i[x] == 'number') { total += i[x] } } return total }
It's problems like 5 that make me sad that IE return i.reduce(function(prev, next) { if (typeof(next) == "object" && next.length) { return arraySum(next) + prev; } if (typeof(next) == "number") { return next + prev; } return prev; }, 0); Something that simple needs to be shimmed on earlier IEs. In fact, I had to look up Array.prototype.reduce for this since I usually use Underscore's. Javascript problems...

Fun little puzzles. First 4 went pretty quickly (~8:00) and then the last one took ~7 minutes Googling around for this so I could test if a variable was an integer... n===+n && n===(n|0) Wish I could see my answers after the fact though! Edit: Read the initial requirements of the puzzle, it says sum all the integers , not all the numbers . People using (typeof i[x] == 'number') just got lucky because the test-cases d…
sum += i[p];
recursion(i[p]);
pretty simple no?

Pretty interesting solution. The first thing that came to my head was a loop, but you just used reduce. What are some scenarios where you would use a reduce over a loop? I use underscore a lot too, and I find myself just using _.each all the time
The bonus upside is that these paradigms also make parallelism quite simple, should it later be necessary.
Thanks for immediately playing audio without asking me first. I know everybody just loves it when web pages do that.
If using chrome, the Chrome Toolbox has a handy mute all tabs feature. I have it muted by default. https://code.google.com/p/chrome-toolbox/
I'm a bit disappointed that it doesn't award points for my heavy use of regex and obscure variable names.
Absolutely! Being under the gun led me, at one point, to have a "longest string in array" method with a statement like
if (i[z].length Fun little puzzles.

if(typeof i[p] === typeof 3){//it's an int sum += i[p]; }else if(typeof i[p] === typeof [3]){//it's an array recursion(i[p]); } pretty simple no?
I dread to think what obscure code I've left behind.
