What is Prototype in Javascript?

#introduction

1. In JavaScript, every function is associated with an object called as prototype.
2. It serves as a blueprint or a template from which other objects can inherit properties and methods.
3. Prototypes are used to achieve inheritance in JavaScript.
4. When you access a property or method on an object, JavaScript first looks for that property or method directly on the object itself. If it doesn't find it there, then it looks at the object's prototype, and continues up the prototype chain until it either finds the property/method or reaches the end of the chain (where the prototype is null).
5. This allows us to define common properties and methods in a prototype, and all objects that inherit from that prototype will have access to those properties and methods.

1. The reference of prototype object is stored in _ _proto_ _
2. When an object is created a prototype object is not created instead the object will have reference of the prototype object (from which properties are to be inherited) referred using _ _proto_ _.

1. Prototypal inheritance is a fundamental concept in JavaScript's object-oriented programming model.
2. It allows objects to inherit properties and methods from other objects, forming a prototype chain.
3. In JavaScript inheritance is achieved using prototype hence it is known as Prototypal Inheritance.

1. The prototype chain is a mechanism in JavaScript that allows objects to inherit properties and methods from other objects.
2. The prototype chain forms a hierarchy of objects, where each object's prototype is linked to its parent object's ptototype, creating a chain of inheritance.
3. By following this chain, objects can inherit properties and methods from their prototype objects.
