# --description--

In some cases, you can destructure the object in a function argument itself.

Consider the code below:

```js
const profileUpdate = (profileData) => {
  const { name, age, nationality, location } = profileData;
  // do something with these variables
}
```

This effectively destructures the object sent into the function. This can also be done in-place:

```js
const profileUpdate = ({ name, age, nationality, location }) => {
  /* do something with these fields */
}
```

When `profileData` is passed to the above function, the values are destructured from the function parameter for use within the function.

# --instructions--

Use destructuring assignment within the argument to the function `half` to send only `max` and `min` inside the function.

# --hints--

`stats` should be an `object`.

```js
assert(typeof stats === 'object');
```

`half(stats)` should be `28.015`

```js
assert(half(stats) === 28.015);
```

Destructuring should be used.

```js
assert(__helpers.removeWhiteSpace(code).match(/half=\({\w+,\w+}\)/));
```

Destructured parameter should be used.

```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;
```
