Awesome Quiz: Share how you did your project!

Oh yeah, and after that I attempted to add certain touch-events for phones and iPads, but ended up deleting that because one: I botched it and two: figured out that I didn't need it in the end because tapping the answer button on a touch screen already translates to a mouse"click" so to speak.

Hey the important part is getting through any part and the trail and error. I love the fact he went through it in detail. I was able to finish my through with no real issue except I had to MDN 'nextsibling'. But checking references are part of the job anyways. Andrew and I came to different solutions but a lot of overlap, so I can tell I picked up some of the ways he approaches things.

I know you said you end up using a lot of his from the video, but i can't tell which part I can say all of it looks very well organized and readable so great job!

I also incorporated the results to show each question and what you got right or wrong. That was fun to extend it.

Nice! Its very clean and readable, I like it. Great job man!

Yes! Event loops are the essence of UI interacted programs. Fortunately you'll discover that a browsers has it own event loop too. That is what you are doing when you hook a callback on a function. The browsers goes through a event loop your code is just a part of the loop. We can even have our own event loop like Dave's directly responding to new events.

Event loops is basically any loop responding to events as it loops. That it. Obviously such a simple model can become extremely complex and an essential feature.

But essentially YOU are creating the events in the loop. When you click a answer, the loop grabs the click event loops past callbacks see the click event has a function tied to it (the one you tied to it), runs it (your code), comes back around. If nothing happened it keeps looping until the next answer is clicked. Then it loops responds, and loops. Its pretty neat when you think about it.

Here is a good read up, though a bit deep, in event loops in browsers with javascript. http://www.altitudelabs.com/blog/what-is-the-javascript-event-loop/

I checked your project out, it looks very well layout. Variables names are understandable and love the comments. The only comment I have is these variables:

var score = 0;
var question = '';
var option1 = '';
var option2 = '';
var button1 = '';
var button2 = '';
var progress = '';

They are in app.js, you should consider if these really need to be global variables or variables contained in one of your objects, using function to pass in relevant information. I only say this cause your bigger applications if you go down this route will have a unwieldy amount of global variables. BUT this is just something to consider next time.

Thanks David.

Absolutely, those variables are out of control! I meant to clean that up, but after figuring out the event loop, it escaped me. I am not even sure what my reasoning was when I did that now, there was definitely a reason! I just can't recall what it was. I think I will clean it up for the practice though, thanks for pointing it out!
