JavaScript Inheritance Tutorial

About This Tutorial

Inheritance is a fundamental concept in object-oriented programming that allows objects to inherit properties and methods from other objects. Unlike classical languages like Java or C++, JavaScript uses prototypal inheritance - a powerful and flexible system that's unique to JavaScript.

This tutorial covers both traditional prototypal inheritance and modern ES6 class syntax, helping you understand how JavaScript's inheritance model works under the hood and how to use it effectively in your applications.

What You'll Learn

• Understand prototypal inheritance and the prototype chain
• Master ES6 class syntax and the extends keyword
• Use super to call parent constructors and methods
• Implement method overriding and property inheritance
• Understand the difference between prototypal and classical inheritance
• Apply inheritance patterns to real-world problems
• Avoid common inheritance pitfalls

Prerequisites

Understanding of JavaScript objects, functions, and the 'this' keyword. Familiarity with constructor functions is helpful but not required.
