Try to call public method "myPublicMethod" on "M圜lass" The same will happen if you try to call public method on a class without instantiating it first. If you create a an instance of that class, and try to call some static method on that instance, JavaScript will return TypeError. These methods can be called only on the class in which they are defined. When it comes to static methods, remember one thing. The method will become static automatically. In this case, you don’t have to use the static keyword. Then, outside the class, you can add new method to this class using dot notation. Try to call static method "myStaticMethod" on "M圜lass" When you do this make sure to prepend the method with the static keyword. First, you can create new class and define a new method inside it. When you want to create one, you can do it in two ways. Static methodsĪs you now know, creating static methods is quick. However, you can’t call them on the class in which they are defined unless you instantiate it. Which also means that you can call them on all instances. This means that they will be accessible for all instances. Note: All methods defined in a class are by default defined as public. One thing you can do with static properties is keeping count of how many instances some class has. For example, you can use static method to create a method that will help you compare two instances of the class. JavaScript developers usually use static methods and properties something like utility functions and utility properties. Second, you can’t call these methods, and access these properties, on instances of the class in which they are defined. First, you can call static methods, and access static properties, without having to instantiate class in which they are defined. The main difference between static and public methods and properties is two-fold. How are static methods and properties different from public methods and properties? This tells JavaScript that the method or property that follows after this keyword should be defined as static. Every static method and property has to start with the static keyword. You will also learn a bit about class inheritance and how it relates to static properties and methods. In this tutorial, you will learn what static methods and properties are and how they work. Two interesting features of classes are static methods and properties. JavaScript classes are one of the most discussed features of ES6.
