Question

This is my code and everytime when I try to access the (car1.topSpeed) in browser console it shows me an error(car1 is not defined) what to do ?

//Creating a constructer for cars
function GeneralCar(givenName,givenSpeed){
    this.name = givenName;
    this.topSpeed = givenSpeed;
    this.run = function(){
        console.log(`${this.name} is running`);
    }
    this.analyze = function(){
        console.log('This car is slower by ${200 - this.topSpeed} than Mercedes')
    }
}
let car1 = new GeneralCar('Tesla',120);          //Here creating a new car with the help of the constructer(GeneralCar).
let car2 = new GeneralCar('Maruti',80);
console.log(car1,car2);
