How to create prototype in JavaScript

Question

im not understood what exactly for prototype is used

Answer 1

Prototype is related to the object oriented aspect of Javascript. To keep it simple, every object in Javascript has a prototype (eg: Date)

The prototype is a kind of a blueprint for the object.

The following code create an object and then use its prototype to add a method:

function myClass(){
myClass.prototype.myMethod = function(){
console.log('hello world')
}
}
