There are several technical differences between classes (or functions) and simple objects. Namely - presence of "constructor", ability to have static and non-static methods and overall the fact that class can be instantiated. It is easy to reason about. I'm sure there could be listed some additional features, but those are first things that pop into my mind. However, I'd say one of the primary reasons for existence of classes would be familiarity. A lot of developers would have experience with classes in other languages so it is useful to have similar entity in JS.
