Subject: [PATCH] not proved features of class properties

"The property name is not placed into User.prototype. Instead, it is created by new before calling the constructor, it’s a property of the object itself."

you are talking about some features of "class properties" but the example code doesn't show these features. I changed the example code to show that defining property out of the constructor method is different from defining method in class structure.

 The property `name` is not placed into `User.prototype`. Instead, it is created by `new` before calling the constructor, it's a property of the object itself.
