# --description--
|
|
|
|
Puedes añadir nuevas propiedades a los objetos de JavaScript existentes de la misma manera que los modificarías.
|
|
|
|
Así es como podríamos agregar una propiedad `bark` a nuestro objeto `ourDog`:
|
|
|
|
`ourDog.bark = "bow-wow";`
|
|
|
|
o
|
|
|
|
`ourDog["bark"] = "bow-wow";`
|
|
|
|
Ahora cuando evaluemos `ourDog.bark`, obtendremos su ladrido, `bow-wow`.
|
|
|
|
Ejemplo:
|
|
|
|
```js
|
|
var ourDog = {
|
|
"name": "Camper",
|
|
"legs": 4,
|
|
"tails": 1,
|
|
"friends": ["everything!"]
|
|
};
|
|
|
|
ourDog.bark = "bow-wow";
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Añade una propiedad `bark` a `myDog` y establécela a un sonido de perro, como "guau". Puedes usar tanto la notación de puntos como la notación de corchetes.
|
|
|
|
# --hints--
|
|
|
|
Debes agregar la propiedad `bark` a `myDog`.
|
|
|
|
```js
|
|
assert(myDog.bark !== undefined);
|
|
```
|
|
|
|
No debes agregar `bark` a la sección de configuración (setup).
|
|
|
|
```js
|
|
assert(!/bark[^\n]:/.test(code));
|
|
```
|
|
|
|
# --seed--
|
|
|
|
## --after-user-code--
|
|
|
|
```js
|
|
(function(z){return z;})(myDog);
|
|
```
|
|
|
|
## --seed-contents--
|
|
|
|
```js
|
|
// Setup
|
|
var myDog = {
|
|
"name": "Happy Coder",
|
|
"legs": 4,
|
|
"tails": 1,
|
|
"friends": ["freeCodeCamp Campers"]
|
|
};
|
|
|
|
// Only change code below this line
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
var myDog = {
|
|
"name": "Happy Coder",
|
|
"legs": 4,
|
|
"tails": 1,
|
|
"friends": ["freeCodeCamp Campers"]
|
|
};
|
|
myDog.bark = "Woof Woof";
|
|
```
