Yep! That covers everything! Thanks a lot!

My so called past experience is basically nothing xD. I just like to mess around and I find this interesting but confusing.

The var x = {} reminds me of learning about sets in math. Is var x = {} basically that the set that's x is currently empty?

Out of curiosity, when you have var x = { a: 1 } can you only get the a from x? That is, var a = { x: 3 } isn't going to affect anything?
