basic class inheritance example using extends and super keyword

suggest change

A generic Car class has some car property and a description method

class Car{
    name:string;
    engineCapacity:string;

    constructor(name:string,engineCapacity:string){
        this.name = name;
        this.engineCapacity = engineCapacity;
    }

    describeCar(){
        console.log(`${this.name} car comes with ${this.engineCapacity} displacement`);
    }
}

new Car("maruti ciaz","1500cc").describeCar();

HondaCar extends the existing generic car class and adds new property.

class HondaCar extends Car{
    seatingCapacity:number;

    constructor(name:string,engineCapacity:string,seatingCapacity:number){
        super(name,engineCapacity);
        this.seatingCapacity=seatingCapacity;
    }

    describeHondaCar(){
        super.describeCar();
        console.log(`this cars comes with seating capacity of ${this.seatingCapacity}`);
    }
}
new HondaCar("honda jazz","1200cc",4).describeHondaCar();
