What is the difference between Prototype and an Object?

Question

I use new to create objects in javascript and for what I noticed very superficially there is not a big difference between the instance with new and using the prototype.

What’s the difference and what advantage of using the prototype?

Answer 1

Object in Javascript inherits the properties and methods of your Prototype.

This is the Prototype:

function Pessoa(nome, idade) {
    this.nome = nome;
    this.idade = idade;
}

This is the Object:

var objeto = new Person("Hudson", "26");
console.log(objeto.nome);

Advantage is the same as in Object Oriented, you can read this article here
