### cmd.exists
| name | return value | description |
|------------|-------------------------|---------------|
| `exists` | `[true or false, ...]` | Checks if each value passed in exists (not null or undefined). |
The following example checks the existence of the values. Only null and undefined count as not existing:
```js
cmd.exists.with(null, undefined, false, '', 0, true);
// [false, false, true, true, true, true]
```
