carlosvega20 / Js Inheritance
Created December 4, 2015 06:10
prototype chain
//Inheritance
var Mass = function () {this.material = "rock"; console.log("init Mass")};
var Planet = function (name) {Mass.call(this); this.name = name || "Planet"; console.log("init "+this.name)};
Planet.prototype = Object.create(Mass.prototype);
Planet.prototype.constructor = Planet;
var earth = new Planet("earth");
// Second Way
Hablar sobre variables(fuerte tipado),
luego funciones (como se crean function, var function, arrow function),
luego scopes (var, const, let)
luego variables como templates
Classes, interfaces, herencia (polimorfismo, encapsulamient)
luego hablar sobre OOP con classes y extend
vs functional programing( fp are verbs, oop is nouns)
