>int bool String Object Why do some types start with lowercase and some with uppercase letter. Why not use a sensible naming convention?

Primitives and objects, it kind of makes sense but I do see your point.

But the thing is, they are not primitives:

> Although you might expect int and double to be primitive types, they're actually interfaces that extend the num interface. This means that int and double variables are also nums.

That's actually kind of like Haskell.
