Tell us what’s happening:
// Custom code - trying to understand inheritance
I am getting the output as :
Vroooooooooom
Undefined
Why am I getting the “undefined” part in the response?
Your code so far
let Vehicle = function (tires,color,engine){
this.tires = tires;
this.color = color;
this.engine = engine;
}
Vehicle.prototype = {
constructor: Vehicle,
steering: true,
drive: function(){
console.log("Vroooooooooom");
}
};
let bus = new Vehicle(6,"red","150 bhp");
console.log(bus.drive());
