This.price = this.price -(this.price * discount)
This is known as a mutator, as it changes the underlying code, a more sustainable way to keep the original prices would be this
Return this.price -(this.price * discount)
Then there would be no underlying data manipulation, then if you wanted to you could create a set price method.
also, this is hypothetical, I don't remember all the JavaScript syntax, so you will have to appropriately apply what I said to JavaScript rules
