Prototype In JavaScript _ JavaScript Object Prototype _ Prototype Inheritance JavaScript

In JavaScript, every object has a prototype. The prototype is an object that contains the default properties and methods for the object. When an object is created, it inherits the properties and methods of its prototype. This is called prototype inheritance. The prototype of an object can be accessed using the __proto__ property. The __proto__ property is a hidden property that is not accessible in the normal way. The following code defines an object called person and assigns it the prototype of the Object constructor function: const person = new Object(); person.__proto__ = Object.prototype; The person object now inherits the properties and methods of the Object constructor function. The prototype can also be used to add properties and methods to objects. The following code adds a property called name to the prototype of the person object: person.__proto__.name = "John Doe"; The name property is now available to all objects that inherit from the person object. Prototype inheritance is a powerful way to create reusable code. It allows you to define common properties and methods in a prototype object and then inherit those properties and methods from other objects. I hope this summary is helpful. Please let me know if you have any other questions.
