![]() The sharable methods are added to this Vehicle class.If no constructor is defined, this will be an empty function. ES6 provides a separate function called constructor which acts as the constructor function for the given class. Let's go through the code and see what's happening. This example is a replica of the above example demonstrated. The following code shows how object-oriented programming can be achieved using constructor methods.įunction Car ( model, hasFuel, color, name, cost, engineType ) var lambo = new Car ( 'gallardo', true, 'yellow', 'Lamborighini', 20000, 'petrol' ) Ĭonsole. Each constructor function contains all the private methods and variables, along with added inheritable properties to perform a given set of operations. In the function-based inheritance, we define a constructor function and add the properties(methods and objects) which can be inherited by other constructors. Function-based inheritance and encapsulation This article will aim at explaining two ways in which OOP can be achieved in javascript. In javascript, Inheritance and Encapsulation are the two techniques that can be used under the hood of Object-oriented programming. Polymorphism: Objects can share the same interface, however, the way they are accessed defines its underlying functionality.Meaning, the object holds data and methods encapsulated inside it to perform all the operations required. Encapsulation: Every object is responsible for handling a complete set of functionalities. ![]() Inheritance: Objects can inherit methods and properties from other objects.The 3 main valuable techniques object-oriented programming provides us are On top of this, ES6 has now introduced a new way of implementing OOP in Javascript. Since javascript already provides the prototype attribute on every object, using this object-oriented programming can be achieved in javascript. Everything translates into an object (Functions, Arrays, Strings, Objects). In javascript objects are the building blocks of our application. Javascript Prototype: Inner workings of Objects.In Javascript, however, OOP is implemented using Function (Usage of ES6 provides class model too, more on that later). In most of the traditional programming languages, object-oriented programming is implemented with the help of Class. The object-oriented programming refers to a paradigm in which structured, reusable pieces of code called objects are created, and its functionalities are borrowed by several other pieces of code.
