Is anyone aware of a way with JS to detect interaction with the native UI in mobile Safari. An example event would be a click on the URL bar or the bookmarks icon. I'd like to be able to trigger a change on the page with JS on these events.
Any ideas?
No, JavaScript does not have access to these events. You would need to use a plug-in.
Your best hope is to detect the mouse leaving the browser pane.

This site is pretty cool, http://pharrellwilliams.com/, and I'm wondering what function makes the users can scroll in any direction and the size of page is endless.
This is the library that the website uses:
http://www.pixijs.com/
https://github.com/pixijs/pixi.js
It shows you when you open up the inspector and take a look at the console.
No problem, make a div that's HUGE, like 10,000px (hardcoded!) in width or something that's way bigger than any possible screen size, and however high you need it to be. Then, fill with content. Boom! Your done.

When a YouTube video goes full screen, it is relative to the monitor rather than the browser.
How can I trigger a browsers full screen mode to display a webpage relative to the monitor with JS?
There's a fullscreen browser API in most modern browsers. You can invoke them in Javascript with commands like
if(document.fullscreenEnabled){
document.getElementById("myimage").requestFullscreen();
}
More info at https://www.sitepoint.com/use-html5-full-screen-api/
Keep in mind you'll have to add much more fullscreen handling code in addition to this.

You can use an iframe and set iframe.document.designMode = "On"; using javascript.
then use iframe.document.execCommand(aCommandName,aShowDefaultUI,aValueArgument);

I have written in javascript two different ways to hover over links and have the background of the window change color, one using event delegation and one not.
How do check which option is best performance wise (probably checking something in the browser developer tools)?
From reading about conventions I have learned that event delegation is the way to go but the code seems less clear and readable so I want to check if does actually perform better.
In Chrome Developer Tools you can use the Timeline section and create a recording of these events and time how long they take.

First poster here, but I wanted to know if there was anyway that it was possible to customize the JavaScript prompt boxes without using jQuery? I'm wanting to keep my site vanilla as possible. Thanks.
You can create your own modal dialog boxes. However you cannot customize how, for example, window.alert("Hello!") would look. That is completely up to the browser manufacturer.
create a 'div' and show that using an event.
