Lecture 200:- What is a Prototype
In JavaScript, a prototype is an object that is associated with every function and object by default. It provides a way to share properties and methods between objects, and allows inheritance to take place.
Each object in JavaScript has an internal link to another object called its prototype. When a property or method is accessed on an object, JavaScript first looks for that property or method on the object itself. If it can't find it, it then looks for it on the object's prototype. If it can't find it there, it looks on the prototype's prototype, and so on, until it reaches the end of the prototype chain.
Prototypes are used to create objects that share properties and methods, without having to create them individually for each object. They can also be used to implement inheritance, where objects inherit properties and methods from a parent object.
In JavaScript, the prototype of an object can be accessed using the prototype property of the object's constructor function.
