super method depreciation on js code example

Example 1: extended class call method from super in javascript

// this is how we call method from a super class(i.e MAIN CLASS) to extended class
class Person {
 constructor(name, age) {
  this.name = name;
  this.age = age;
 }
greet() {
  console.log(`Hi, all my name is ${this.name}`);
 }
}

class Employee extends Person {
 constructor(name, age, employer) {
  super(name, age);  // NOTE : super must call before accessing (this)
  this.employer = employer;
 }

 greeting() {
  super.greet();  // this is how we call
  console.log(`I'm working at ${this.employer}`);
 }
}

let Steve = new Employee('Xman', 25 , 'Skynet');
Steve;
Steve.greeting(); // check by consoling MATE

Example 2: javascript super

class Parent {
  constructor() {}
  method() {}
}
class Child extends Parent {
  constructor() {
    super() // Parent.constructor
    super.method() // Parent.method
  }
}
