What are some super functions in JavaScript?

Super functions in JavaScript refer to functions that can access properties and methods of their parent class. They are often used in object-oriented programming.

Can you give me an example of a super function?

Sure! In a class that extends another class, you can use super() to call the parent class's constructor or methods. For example:

class Animal {
    constructor(name) {
        this.name = name;
    }
}

class Dog extends Animal {
    constructor(name, breed) {
        super(name);
        this.breed = breed;
    }
}

Here, super(name) calls the constructor of the Animal class.

What are the benefits of using super functions?

Using super functions helps in code reusability and maintaining a clean inheritance structure. It allows derived classes to leverage the functionality of their parent classes.

Are there any limitations to using super functions?

Yes, one limitation is that super() can only be called within the constructor of a derived class. Additionally, it can only be used in classes that extend another class.
