The super keyword refers to superclass (parent) objects. it is used to call superclass methods, and to access the superclass constructor. the most common use of the super keyword is to eliminate the confusion between superclasses and subclasses that have methods with the same name. to understand the super keyword, you should have a basic understanding of inheritance and polymorphism. Super isn't unique to javascript — many programming languages, including java and python, have a super keyword that provides a reference to a parent class. javascript, unlike java and python, is not built around a class inheritance model. instead, it extends javascript’s prototypal inheritance model to provide behavior that’s consistent with class inheritance.

Difference Between Super And This In Java Geeksforgeeks
We can use super as well this only once inside constructor. if we use super twice or this twice or super it is upto you that whether you use super or this or not because if we are not using this or super then by inside main we have new base then flow goes to no. With super the superclass no-argument constructor is called. with super (parameter list), the superclass constructor with a matching parameter list is called. note: if a constructor does not explicitly invoke a superclass constructor, the java compiler automatically inserts a call to the no-argument constructor of the superclass.
