Private Properties in Inheritance in OOP in JavaScript

Private properties are not inherited. But the child can manipulate them through the parent's public methods. Let's see in practice. Let's have the following parent class with a private property and its getter and setter:

javascriptclass User {
  #name;
  
  setName(name) {
    this.#name = name;
  }
  getName() {
    return this.#name;
  }
}

Let the following child inherit from the parent:

javascriptclass Student extends User {
  
}

Let's create a descendant object:

javascriptlet student = new Student;

Let's use the parent's method to write its private property:

javascriptstudent.setName('john');

Let's use the parent's method to read its private property:

javascriptlet name = student.getName();
console.log(name);

javascriptclass User {
  #name;
  #surn;
  
  setName(name) {
    this.#name = name;
  }
  getName() {
    return this.#name;
  }
  
  setSurn(surn) {
    this.#surn = surn;
  }
  getSurn() {
    return this.#surn;
  }
}

javascriptgetFull() {
  return this.#name + ' ' + this.#surn;
}
