❗️Что будет на выходе:

"use strict";

function createCounter() {
  let count = 0;

  return {
    increment() { count++; },
    get value() { return count; },
    toString() { return `Counter: ${count}`; }
  };
}

const counter = createCounter();
counter.increment();
counter.increment();
counter.increment();

try {
  counter.value = 99;
} catch (e) {
  console.log(`${e.constructor.name}: ${counter}`);
}

Ответ: TypeError: Counter: 3
