### average
|
|
|
|
Returns the average of an of two or more numbers.

Use `Array.reduce()` to add each value to an accumulator, initialized with a value of `0`, divide by the `length` of the array.
|
|
|
|
```js
|
|
const average = (...nums) => [...nums].reduce((acc, val) => acc + val, 0) / nums.length;
|
|
```
|
|
|
|
```js
|
|
average(...[1, 2, 3]); // 2
|
|
average(1, 2, 3); // 2
|
|
```
