Here, we will learn the benefits of the inheritance concept in JavaScript.Code reusability − The child class can inherit the properties of the parent class. So, it is the best way to reuse the parent class code. Functionality extension − You can add new properties and methods to extend...
The following is an example in the style of the functional pattern for inheritance as explained in Douglas Crockford's JavaScript: The Good Parts. It contains the definition for a phone type as well as a subtype smartPhone. var phone = function(spec) { var that = {}; that.getPhoneNumber...
In the above example, we have defined Person class (function) with FirstName & LastName properties and also added getFullName method to its prototype object. Now, we want to create Student class that inherits from Person class so that we don't have to redefine FirstName, LastName and get...
JavaScript is a class-free, object-oriented language, and as such, it uses prototypal inheritance instead of classical inheritance. This can be puzzling to programmers trained in conventional object-oriented languages like C++ and Java. JavaScript's prototypal inheritance has more expressive power than...
In the above example, theStudentclass inherits all the methods and properties of thePersonclass. Hence, theStudentclass will now have thenameproperty and thegreet()method. Then, we accessed thegreet()method ofStudentclass by creating astudent1object. ...

To add getters and setters in the class, use the get and set keywords.Example Create a getter and a setter for the "carname" property: class Car { constructor(brand) { this.carname = brand; } get cnam() { return this.carname; } set cnam(x) { this.carname = x; }}const myCar ...
JavaScript Copy Justification For people coming from other OOP languages, the class keyword is used to define classes in a more recognizable manner. A subclass is created using the extends keyword. Dog extends Animal in this instance. As in the prototype example, the Dog class overrides the spea...
A common way is to use a JavaScript library — most of the popular options have an easy set of functionality available for doing inheritance more easily and quickly.CoffeeScriptfor example providesclass,extends, etc. A further exercise In ourOOP theory section, we also included aStudentclass as...
