![]() ![]() This creates a something called prototype chain. Because a prototype itself is also another object, the prototype has its own prototype. Every object has its own property called prototype. This means that you can use general objects to share. Introduction to JavaScript prototype In JavaScript, objects can inherit features from one another via prototypes. In case of Function’s prototype additional properties will be visible to all other objects of same constructor function. If you dig into a little more detail, you will discover that JavaScript is a prototype-based language. ![]() In case of Object’s prototype properties will not be visible to other objects. We can add additional properties to prototype object. It returns the primitive value of the object.Īs discussed earlier, prototype is an object which is associated to every object in JavaScript. It returns true if the specified property is enumerable otherwise return false. It returns true if the specified object is in the prototype chain of the object this method is called upon otherwise return false. It returns true if an object contains the specified property as a direct property of that object and not inherited through the prototype chain otherwise returns false. ![]()
