JS Getters and Setters

Getters and setters allow you to get and set object properties via methods.

This example uses a lang property to get the value of the language property:

// Create an object:
const person = {
  firstName: "John",
  lastName: "Doe",
  language: "en",
  get lang() {
    return this.language;
  }
};

// Display data from the object using a getter:
document.getElementById("demo").innerHTML = person.lang;
