apa itu prototipe javascript

* Prototype

-Every object in JavaScript has a built-in property,
which is called its prototype. 

-The prototype is itself an object, so the prototype will 
have its own prototype, making what iss called a prototype chain.

-The chain ends when we reach a prototype that has null for 
its own prototype.

-Prototypes are the mechanism by which JavaScript objects inherit
features from one another

const  arr = [1,2,3,4]

// proto type : arr.__proto__
// prototype chain : arr.__proto__.__proto__.__proto__
