class Counter {
  #count = 0;

  increment() {
    this.#count++;
    console.log(this.#count);
  }

  getCount() {
    return this.#count;
  }
}

const counter = new Counter();
counter.increment(); // Output: 1
console.log(counter.getCount()); // Output: 1
console.log(counter.#count); // Error: Private field '#count' must be declared in an enclosing class
