Description

Ahora ha visto dos tipos de propiedades: propiedades own y propiedades de prototype . Own propiedades Own se definen directamente en la instancia del objeto en sí. Y las propiedades del prototype se definen en el prototype .

function Bird(name) {
  this.name = name; //own property
}

Bird.prototype.numLegs = 2; // prototype property

let duck = new Bird("Donald");

Así es como se agregan duck's propiedades own duck's a la matriz ownProps y las propiedades de prototype a la matriz prototypeProps :

let ownProps = [];
let prototypeProps = [];

for (let property in duck) {
  if(duck.hasOwnProperty(property)) {
    ownProps.push(property);
  } else {
    prototypeProps.push(property);
  }
}

console.log(ownProps); // prints ["name"]
console.log(prototypeProps); // prints ["numLegs"]

Instructions

Agregue todas las propiedades own de beagle a la matriz ownProps . Agregue todas las propiedades prototype de Dog a la matriz prototypeProps .

Tests

tests:
  - text: La matriz <code>ownProps</code> debe incluir <code>&quot;name&quot;</code> .
    testString: 'assert(ownProps.indexOf("name") !== -1, "The <code>ownProps</code> array should include <code>"name"</code>.");'
  - text: La matriz <code>prototypeProps</code> debe incluir <code>&quot;numLegs&quot;</code> .
    testString: 'assert(prototypeProps.indexOf("numLegs") !== -1, "The <code>prototypeProps</code> array should include <code>"numLegs"</code>.");'
  - text: Resuelva este desafío sin usar el método <code>Object.keys()</code> .
    testString: 'assert(!/\Object.keys/.test(code), "Solve this challenge without using the built in method <code>Object.keys()</code>.");'

Challenge Seed

function Dog(name) {
  this.name = name;
}

Dog.prototype.numLegs = 4;

let beagle = new Dog("Snoopy");

let ownProps = [];
let prototypeProps = [];

// Add your code below this line

Solution

function Dog(name) {
  this.name = name;
}

Dog.prototype.numLegs = 4;

let beagle = new Dog("Snoopy");

let ownProps = [];
let prototypeProps = [];
for (let prop in beagle) {
  if (beagle.hasOwnProperty(prop)) {
    ownProps.push(prop);
  } else {
    prototypeProps.push(prop);
  }
}
