class InstPrivateClass {
  #privateField1 = 'private field 1'; // (A)
  #privateField2; // (B) required!
  constructor(value) {
    this.#privateField2 = value; // (C)
  }
  /**
   * Private fields are not accessible outside the class body.
   */
  checkPrivateValues() {
  console.log(this.#privateField1); // output -> 'private field 1'
  console.log(this.#privateField2); // output -> 'constructor argument'
