Respond in the comments of this issue with:

1. What is something you learned that was particularly surprising/interesting?

• I didn't know that if you don't specify the var before declaring a variable in javascript, it will be a global variable. That seems a little dangerous if you forget that!
• I also did not know that $() will always return a jQuery object even if the selector isn't found (so you want to look at the length of the array that's returned to make sure it's not empty)
• Namespaced events seem incredibly useful.
• The event object is also very cool.

2. What was something you already knew?

• Much of the JavaScript Basics was review for me.
• Traversing the DOM was also somewhat review (though I wish we had this reading in mod 3!).
• I knew some the shorthand methods for event handling.

3. Was there anything you feel you still don't understand?

• I think I still need another example of event bubbling to really understand it.
• I am still not sure what jqXHR and deferred is and how to use it.
