Object-oriented programming in JavaScript
All the objects in JavaScript are inherited from an object. JavaScript provides different patterns to adhere to the object-oriented programming (OOP) principles when building applications. There are different patterns, such as constructor patterns, prototype patterns, and object literal representation, and, with ECMAScript 6, a completely new way of representing objects through classes and inheriting a base class using the extends keyword.
In this section, we will see how we can implement the OOP principles with different methodologies.
Creating objects
A class represents the structure of an object and every class has certain methods and properties used by the object, whereas an object is an instance of a class and is known as a class instance.
JavaScript is a prototype-based language and based on objects. In a class-based language such as C# and Java, we have to first define the class that contains some methods and properties and then use its constructor...
