So it uses a lot of console logging, and created objects for its own demonstrations. It went into how you'd add a method onto a function, which is very different from how you would in c#. It was actually very good at explaining how to determine if an object has a property, explaining the differences between null and undefined. I spent a good portion of my time on this since it is a little different from c#.
The book did touch on array methods, but didn't go into depth. I'm glad about this because as I said earlier, it was longer than it needed to be.
I am excited though because I see the next part is called "Working with jQuery".
