5:54 -> let myCar = new Toyota();
=> what does mean of the 'new' keywords? Is it like a object in function and it's veil on the mystery in my eyes. Could you let me know some a bit or reference where is there on MDN?

Hi sir, what are RPA and Machine Learning? Are these two completely different technology? Does a Devops guy need to learn these technologies to enhance his career, I mean any relation of these technologies with DevOps? Do you provide any course on any of these? Please reply.

Thanks for the tutorial! i am currently trying to build a chess engine and i couldn't get the syntax right 💀

[pegaproject]

class Car{ //class

setName(name){ //method
this.name = name; //set name value to clasee variable
}

startEngine(){
console.log ('Engine started for '+this.name);
}

stoptEngine(){
console.log ('Engine stopped for '+this.name);
}


}

class Toyota extends Car{ // Car is Parent class Toyota is child class of Car.
//so all functions & methos we can call inherince from Parent class.
//Using extends key word//
topSpeed(speed){
console.log ('Top speed for '+this.name+' is '+speed) //this.name from parent class inside function
//+speed from current class function.//

}


}

let myCar = new Toyota(); ///IMP..Object for Toyota class
//Note we can acces propries & methods of Parent class(Car) of Toyota class...
myCar.setName('Camry');
myCar.startEngine();
myCar.stoptEngine();
myCar.topSpeed(200);
