In the classical inheritance, methods from base class get copied into derived class. In JavaScript, inheritance is supported by using prototype object. There are two way for apply inheritance property. 1. Using extends keyword 2. Using prototype function **Using extends keyword** ``` Syntax: class child-class-name extends parent-class-name{ constructor(){ // parent constructor calling using super() // variable initialization } } ``` ``` Example

Use the 'extends' keyword to inherit all methods from another class.

Use the 'super' method to call the parent's constructor function.

``` **Using prototype function** Let's see how we can achieve inheritance functionality in JavaScript using prototype object. Let's start with the Person class which includes FirstName & LastName property as shown below. ``` ``` \ ### Answer by Ethan Karla Inheritance is an important concept in object-oriented programming, In classical inheritance, methods from the base class get copied into the derived class. In JavaScript, inheritance is supported using prototype objects. There is two way for apply inheritance property. ## Features of inheritance 1. inherited the parent property 2. increase code reusability 3. fast accessing 4. improve security ## Using extends keyword ``` Syntax class child-class-name extends parent-class-name{ constructor(){ // parent constructor calling using super() // variable initialization }} ``` ``` Example

``` ## Using prototype function ``` class_name.prototype.prototype_name= function() { statement }; ``` ``` ``` \ --- Original Source: https://answers.mindstick.com/qa/93755/what-is-inheritance-in-javascript-explain-the-all-inheritance Copyright © MindStick Software Pvt.
