In derived classes, super() must be called before you use 'this'. Leaving this out will cause a reference error.
Just for information. I had faced this issue.may be useful for someone.

Very useful and a good explanation. I have been battling classes for 2 days now and it is all getting much clearer now. Big thank you!

I was trying to figure out how to do the Hackerrank challenge on classes and inheritances and did not understand how to use super to inherit stuff from the parent class, but this video explained it perfectly!

Cant we user the render return function in normal javascript class?

[jaiylonbabb]

How would I be able to put all the instances in the User class in an array, iterate through the array, and print all the objects?

[natetolbert]

Can JS classes have multiple constructors defined, as they can in languages such as Java?

[FaishalHanif]

Thank you, finally i can understand it

[sebastienbertrand]

You could have fill "memberPackage" instead of "this.package" in the string, right ?

[matthewdavies]

but why does super also take the same parameters? does super overwrite the subclass ? or subclass overwrite super?.
when you call mike.getPackage it's console logging this.username which is taking the username from Member subclass, so why does Member then also need to have super and its parameters? it's not using the parent class at this moment is it?
