### sample
|
|
|
|
Returns a random element from an array.
|
|
|
|
Use `Math.random()` to generate a random number, multiply it by `length` and round it of to the nearest whole number using `Math.floor()`.
|
|
This method also works with strings.
|
|
|
|
```js
|
|
const sample = arr => arr[Math.floor(Math.random() * arr.length)];
|
|
// sample([3, 7, 9, 11]) -> 9
|
|
```
