How Do I Change The Property?

Question

var money = 100000
const car = {
price:5000,
bought:false,
buy: function(){
if(car.bought == false && money > car.price){
money = money - car.price;
// i want to change the bool bought to true but idk how
}
}
}

Answer 1

this.bought = true; // "this" refers to the car object

Answer 2

Object members in JS can't be accessed by reference inside of the object's initialization, because the variable holding it is assigned a reference to the object AFTER all key/value pairs have been defined. So when you refer to `car.bought` from inside the object, the environment doesn't know yet that `car` holds a reference to `bought`, instead thinking `car` is an undefined variable.

What you could do though is use the 'this' keyword instead, which refers to the object's context.

const car = {
price: 5000,
bought: false,
buy: function () {
if (this.bought == false && money > this.price) {
money = money - this.price;
}
}
}
