Javascript – Classes

Javascript introduced classes in ES6 (ECMAScript2015). To define a class you need to use the class keyword and add a constructor method which is executed when a new object is created. You must declare a class before you use it.

In classes, the functions are defined only with their name, without the function keyword

Static methods

Static methods are created using the static keyword. They can be used without an object creation.

You do not need to create an object to call a static method.

getters and setters

You use getters and setters if you want to do something special with the value before you set them or return them. You declare them using the get and set keywords.
