Prototype In JavaScript. Prototype is basically an object called prototype object. We can add methods/properties in prototype object. Whatever function we create in javascript comes with prototype property through javascript engine.

Whenever we create a JavaScript function, JavaScript adds a prototype property to that function. A prototype is an object, where it can add new variables and methods to the existing object. i.e., Prototype is a base class for all the objects, and it helps us to achieve the inheritance. The prototype property allows you to add new properties and methods to existing object types. Note: Prototype is a global property which is available with almost all JavaScript objects.

JavaScript is a prototype based language, so, whenever we create a function using JavaScript, JavaScript engine adds a prototype property inside a function, Prototype property is basically an object (also known as Prototype object), where we can attach methods and properties in a prototype object, which enables all the other objects to inherit these methods and properties. The prototype is an object that is associated with every functions and objects by default in JavaScript, where function's prototype property is accessible and modifiable and object's prototype property (aka attribute) is not visible.
