Prototypal Inheritance using __proto__ in JavaScript Last Updated : 02 Jun, 2020 Comments Improve Suggest changes 15 Likes Like Report Every object with its methods and properties contains an internal and hidden property known as [[Prototype]]. The Prototypal Inheritance is a feature in javascript used to add methods and properties in objects. It is a method by which an object can inherit the properties and methods of another object. Traditionally, in order to get and set the [[Prototype]] of an object, we use Object.getPrototypeOf and Object.setPrototypeOf. Nowadays, in modern language, it is being set using __proto__. Syntax: ChildObject.__proto__ = ParentObject Example In the given example, there are two objects 'person' and 'GFGuser'. The object 'GFGuser' inherits the methods and properties of the object 'person' and further uses them. html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <title>prototype</title> </head> <body> <script> // object person let person = { talk: true, Canfly() { return "Sorry, Can't fly"; }, }; // Object GFGuser let GFGuser = { CanCode: true, CanCook() { return "Can't say"; }, // Inheriting the properties and methods of person __proto__: person, }; // Printing on console // Property of person console.log("Can a GFG User talk: " + GFGuser.talk); // Method of person console.log("Can a GFG User fly: " + GFGuser.Canfly()); // Property of GFGuser console.log("Can a GFG User code: " + GFGuser.CanCode); // Method of GFGuser console.log("Can a GFG User cook: " + GFGuser.CanCook()); </script> </body> </html> Output Create Quiz Comment H hacksight Follow 15 Improve H hacksight Follow 15 Improve Article Tags : JavaScript Web Technologies JavaScript-Misc Explore JavaScript BasicsIntroduction to JavaScript4 min readVariables and Datatypes in JavaScript6 min readJavaScript Operators5 min readControl Statements in JavaScript4 min readArray & StringJavaScript Arrays7 min readJavaScript Array Methods7 min readJavaScript Strings5 min readJavaScript String Methods9 min readFunction & ObjectFunctions in JavaScript5 min readJavaScript Function Expression3 min readFunction Overloading in JavaScript4 min readObjects in JavaScript4 min readJavaScript Object Constructors4 min readOOPObject Oriented Programming in JavaScript3 min readClasses and Objects in JavaScript4 min readWhat Are Access Modifiers In JavaScript ?5 min readJavaScript Constructor Method7 min readAsynchronous JavaScriptAsynchronous JavaScript2 min readJavaScript Callbacks4 min readJavaScript Promise4 min readEvent Loop in JavaScript4 min readAsync and Await in JavaScript2 min readException HandlingJavascript Error and Exceptional Handling6 min readJavaScript Errors Throw and Try to Catch2 min readHow to create custom errors in JavaScript ?2 min readJavaScript TypeError - Invalid Array.prototype.sort argument1 min readDOMHTML DOM (Document Object Model)8 min readHow to select DOM Elements in JavaScript ?3 min readJavaScript Custom Events4 min readJavaScript addEventListener() with Examples9 min readAdvanced TopicsClosure in JavaScript4 min readJavaScript Hoisting6 min readScope of Variables in JavaScript3 min readJavaScript Higher Order Functions7 min readDebugging in JavaScript4 min read Like
