The super Keyword

Call parent class methods

Use super to call the parent class constructor or methods.

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

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

In subclass constructors, call super() before using this.
