Front End Web Development Techdegree Graduate 14,538 PointsDoes it matter what order you invoke the getter and setter methods? Does get always go before set?
Does set always follow get, or could you put set before get?

But if you're talking about the order they are defined in the class, that makes no difference.

Full Stack JavaScript Techdegree Student 10,331 PointsIn JavaScript the order of function definitions doesn't matter because of function hoisting. Order matters in other languages.
Steven Parker
231,124 PointsMethods aren't hoisted, so don't try to call them before the class is defined.

Full Stack JavaScript Techdegree Student 10,331 PointsThanks for the correction on methods inside classes. Though, in trying to confirm what you've said I've had trouble finding a clear answer for why the order of class methods doesn't matter.
According to MDN's documentation classes are not hoisted. However, I've also read that classes are hoisted, but just not initialized until evaluated thus the reason for not calling a class' functions until after the object is instantiated.
This post also says that hoisting of functions happens within block scope. So am I correct in concluding this is the reason that the order of functions within a class do not matter? Or is it only that we could never have a function inside a class that can directly call another function in that class? I couldn't come up with any.
Steven Parker
231,124 PointsSure, methods can call each other. But since they are all defined together in the class, and all instantiated together, they are all available before you call any of them.

Full Stack JavaScript Techdegree Student 10,331 PointsThanks Steven. That makes sense.

Front End Web Development Techdegree Graduate 14,538 PointsYeah, I meant the order they are defined in the class. Thank you!
