|
我们同样可以删除对象的属性，例如：
|
|
|
|
`delete ourDog.bark;`
|
|
|
|
# --instructions--
|
|
|
|
删除`myDog`对象的`"tails"`属性。
|
|
|
|
# --hints--
|
|
|
|
从`myDog`中删除`"tails"`属性。
|
|
|
|
```js
|
|
assert(typeof myDog === 'object' && myDog.tails === undefined);
|
|
```
|
|
|
|
不要修改`myDog`的初始化。
|
|
|
|
```js
|
|
assert(code.match(/"tails": 1/g).length > 1);
|
|
```
|
|
|
|
# --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;
|
|
```
