# falsy

```js
// usages
chance.falsy()
chance.falsy({ pool: [ NaN, undefined ] })
```
Return a random falsy value (`false`, `null`, `undefined`, `0`, `NaN`, `''`).

```js
chance.falsy();
=> false
```

The default pool can be changed to better meet the needs:

```js
chance.falsy({ pool: [ NaN, undefined ] });
=> NaN
```
