What are getters and setters in JavaScript classes?

Can you explain what getters and setters are in JavaScript classes?

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

How do I define a getter and a setter in a class?

You can define a getter using the get keyword and a setter using the set keyword. For example:

class Person {
  constructor(name) {
    this._name = name;
  }

  get name() {
    return this._name;
  }

  set name(newName) {
    this._name = newName;
  }
}

What is the purpose of using underscores in property names?

The underscore is a convention to indicate that a property is private or intended for internal use only. It helps distinguish between the private property and the public getter/setter.

Can I use getters and setters with other data types?

Yes, you can use getters and setters with any data type, including objects, arrays, and even functions!
