Change js object property getter/setter

Question

Is it possible to change the value of the property getter of an object? let's say we have

const autoIncrementer = (function() {
  let value = 0;

  return {
    incr() {
        value++
    },

    get value() {
        return value
    }
  };
})(); 
function anotherFunctin (){//log smth.}
autoIncrementer.value = anotherFunction;

P.S. I know that this does not do any good, so I just need an explanation of why is this so? and is there any way to achieve this goal?

Look into [`Object.defineProperty`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty) — Heretic Monkey, Nov 30 '20 at 14:19
I answered below. But it seems you need `setter` and auto-incremental getter. Am I right? — vovchisko, Nov 30 '20 at 14:36
@HereticMonkey yes it Absolutely does(answer my question)! thanks — Saro Vilhelm Yekanian, Nov 30 '20 at 15:45

You can use setter along with getter.

let obj = {
  get propName() {
    // getter, the code executed on getting obj.propName
  },

  set propName(value) {
    // setter, the code executed on setting obj.propName = value
  }
};
