typescript inheritance super code example

Example 1: how to extend ts class

class Animal {
  move(distanceInMeters: number = 0) {
    console.log(`Animal moved ${distanceInMeters}m.`);
  }
}

class Dog extends Animal {
  bark() {
    console.log("Woof! Woof!");
  }
}

const dog = new Dog();
dog.bark();
dog.move(10);
dog.bark();Try

Example 2: class inheritance in typescript

// Parent class
class Info {
  protected name: string ;
  constructor(n:string){
    this.name = n ;
  };
  describe(){
    console.log(`Your name is  ${this.name}`);
  }
}

//inherited class (you can overwrite methods of parent class, super is used to
// connect to the parent parameter(s) . )

class Detail extends Info{
  constructor(name:string, public age:number){
    super(name);
  }
  findAge(){
      console.log(`${this.name} age is ${this.age}`)
  }
}

const b = new Detail('jank', 23);
b.describe();
b.findAge();
