Understanding Inheritance in JavaScript

by

What is Inheritance? Inheritance is a fundamental concept in object-oriented programming. It allows one class (a subclass or child class) to acquire the properties and methods of another class (a superclass or parent class). By doing so, subclasses can reuse and build upon the existing functionality, reducing code duplication and improving maintainability. Inheritance in JavaScript … Read more

Understanding Polymorphism in JavaScript

by

What Is Polymorphism? Polymorphism is a fundamental concept in object-oriented programming that refers to the ability of a single interface or method to handle different underlying forms (data types, classes, or behavior). Essentially, it means “many forms.” In simpler terms, polymorphism allows one piece of code to work with different objects in a consistent way. … Read more

Understanding Encapsulation in JavaScript

by

What Is Encapsulation? Encapsulation is an object-oriented programming principle that involves bundling data (properties) and behaviors (methods) together and restricting direct access to some of these components. The idea is to hide internal implementation details and expose a clear and stable interface for interacting with the object. In classical OOP languages like Java or C++, … Read more

Understanding ES6 Classes in JavaScript

by

Introduction to Classes Before ES6 (ECMAScript 2015), JavaScript primarily used constructor functions and prototypes for object creation and inheritance. ES6 introduced classes as syntactical sugar on top of the existing prototype-based inheritance model. Although classes look more like classes in languages such as Java or C++, they still rely on prototypes under the hood. Defining … Read more

Understanding Method Chaining in JavaScript

by

What Is Method Chaining? Method chaining, or a fluent interface, is a programming style that allows you to call multiple methods on an object in a single line, one after another. Instead of performing an operation and then returning a new unrelated value, methods return the current object (this), enabling successive method calls directly on … Read more

Understanding Mixins in JavaScript

by

What Are Mixins? In object-oriented programming, a mixin is a way to add properties and methods from one object to another, thereby mixing behaviors into multiple classes. Mixins provide a form of “multiple inheritance” since JavaScript does not natively support extending multiple classes. Instead, JavaScript uses prototype-based inheritance and typically allows a class to extend … Read more
