This video on Prototypal Inheritance in JavaScript will take you through the basics of how inheritance is integrated into JavaScript before introducing classes. In this tutorial, Javascript Prototypal Inheritance is explained with the help of examples. We’ll also understand the Object.create() method of creating an object in JavaScript. Below are the points we are going to discuss in this JavaScript tutorial for beginners’ video.

What is Object Prototype?
Prototypes are the mechanism by which JavaScript objects inherit features from one another. This video explains how prototype chains work and look at how the prototype property can be used to add methods to existing constructors. An object’s prototype object may also have a prototype object, which inherits methods and properties from, and so on. This is often referred to as a prototype chain and explains why different objects have properties and methods defined on other objects available to them.

What is Prototypal Inheritance?
For instance, we have a Vehicle constructor with its properties and methods, and want to make bike and car as slightly modified variants of it. We’d like to reuse what we have in vehicles, not copy/reimplement its methods, just build a new constructor on top of it. Prototypal inheritance is a language feature that helps in that. prototypal inheritance refers to the ability to access object properties from another object. We use a JavaScript prototype to add new properties and methods to an existing object constructor.

A JavaScript object literal is a comma-separated list of name-value pairs wrapped in curly braces. Constructors encapsulate data, enclosing it in a tidy package. This minimizes the use of global variables which can cause problems when combining code.Whenever we are working with a single object or when we know everything about the properties and the behaviour of an object. We should always use the object literal method. That’s because this method runs faster, and we have to write minimum code while using the object literal method.
