Prototype pattern implementation in JS

prototype.js

//Prototype Pattern
function car (manufacturer, engineType, transmission) {
  this.manufacturer = manufacturer;
  this.engineType = engineType;
  this.transmission = transmission;

  this.showManufacturer = function() {
    console.log("Manufacturer is: "+this.manufacturer);
  }

  this.showEngineType = function() {
    console.log("Engine type is: "+this.engineType);
  }

  this.showTransmission = function() {
    console.log("Transmission is: "+this.transmission);
  }
}


var myCar = new car("BMW", "Petrol", "Manual");
myCar.showManufacturer();
myCar.showEngineType();
myCar.showTransmission();


// added one variable in the class -> isHybrid
car.prototype.isHybrid = true;
// added one method in the class -> startCar
car.prototype.startCar = function () {
  console.log("start my"+this.manufacturer);
}

var myAnotherCar = new car("Tesla", "Electric","automatic",true)
console.log(myAnotherCar.isHybrid);
myAnotherCar.startCar();
