What are getters and setters in JavaScript?

Can you explain what getters and setters are in JavaScript?

Sure! Getters and setters are special methods in JavaScript that allow you to define how properties of an object are accessed and modified.

How do I define a getter and a setter?

You can define them using the get and set keywords. For example:

const obj = {
  _name: 'John',
  get name() {
    return this._name;
  },
  set name(value) {
    this._name = value;
  }
};

This allows you to access obj.name and set it using obj.name = 'Doe';.

What are the benefits of using getters and setters?

They provide a way to control access to object properties, allowing for validation, computed properties, and encapsulation.

Can I use them with classes?

Yes! You can use getters and setters in classes as well, just like in object literals. They work the same way.
