# --description--
在某些情況下,你可以在函數的參數裏直接解構對象。
請看以下代碼:
```js
const profileUpdate = (profileData) => {
const { name, age, nationality, location } = profileData;
}
```
上面的操作解構了傳給函數的對象。 這樣的操作也可以直接在參數裏完成:
```js
const profileUpdate = ({ name, age, nationality, location }) => {
}
```
`profileData` 被傳遞到上面的函數時,從函數參數中解構出值以在函數內使用。
# --instructions--
`half` 的參數進行解構賦值,僅將 `max``min` 的值傳進函數。
# --hints--
`stats` 的類型應該是一個 `object`
```js
assert(typeof stats === 'object');
```
`half(stats)` 應該等於 `28.015`
```js
assert(half(stats) === 28.015);
```
應該使用解構賦值。
```js
assert(__helpers.removeWhiteSpace(code).match(/half=\({\w+,\w+}\)/));
```
應該使用解構參數。
```js
assert(!code.match(/stats\.max|stats\.min/));
```
# --seed--
## --seed-contents--
```js
const stats = {
max: 56.78,
standard_deviation: 4.34,
median: 34.54,
mode: 23.87,
min: -0.75,
average: 35.85
};
// Only change code below this line
const half = (stats) => (stats.max + stats.min) / 2.0;
// Only change code above this line
```
# --solutions--
```js
const stats = {
max: 56.78,
standard_deviation: 4.34,
median: 34.54,
mode: 23.87,
min: -0.75,
average: 35.85
};
const half = ( {max, min} ) => (max + min) / 2.0;
```
