The class type. This is used for serialization and deserialization purposes and internally it can be used to identify classes. When we transform a class in a plain JS object we need a way to recognize which class it was, and the type is the way we do that. It has no other purposes and you should not give one. Hard to reach on instances and please do not use to drive instance’s logic (this.constructor.type). To idenfity a class use instanceof class ( instanceof Rect ). We do not do that in fabricJS code because we want to try to have code splitting possible.
