How to work in Vue in computed with setters?

Question

Vue.js

I’ll say right away: I read the documentation, but I didn’t fully understand it ..

So ..
Imagine that I have a computer:

selectedCarNumber: {
            get: function () {
                return 0
            },
            set: function (value) {
                // что писать, чтобы поменять значение у возвращаемого числа get ?
            }
        },

How is the setter supposed to work?
Something like: and if I want to change the value of the returned number from get - how to be?

Please explain

Answer 1

data() {
  return {
    number: 0
  };
},
selectedCarNumber: {
            get: function () {
                return this.number;
            },
            set: function (value) {
                this.number = value;
            }
        },
