# --description--

We can also delete properties from objects like this:

`delete ourDog.bark;`

Example:

```js
var ourDog = {
  "name": "Camper",
  "legs": 4,
  "tails": 1,
  "friends": ["everything!"],
  "bark": "bow-wow"
};

delete ourDog.bark;
```

After the last line shown above, `ourDog` looks like:

```js
{
  "name": "Camper",
  "legs": 4,
  "tails": 1,
  "friends": ["everything!"]
}
```

# --instructions--

Delete the `"tails"` property from `myDog`. You may use either dot or bracket notation.

# --hints--

You should delete the property `"tails"` from `myDog`.

```js
assert(typeof myDog === 'object' && myDog.tails === undefined);
```

You should not modify the `myDog` setup.

```js
assert(code.match(/"tails": 1/g).length > 0);
```

# --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"],
  "bark": "woof"
};

// Only change code below this line
```

# --solutions--

```js
var myDog = {
  "name": "Happy Coder",
  "legs": 4,
  "tails": 1,
  "friends": ["freeCodeCamp Campers"],
  "bark": "woof"
};
delete myDog.tails;
```
