# isDestroyed()

> Returns whether the call instance has been destroyed.

`isDestroyed()`

<Badge color="green">{"✓"} Prebuilt</Badge> <Badge color="green">{"✓"} Custom</Badge>

Returns `true` if [`destroy()`](/reference/daily-js/instance-methods/destroy) has been called on this instance. A destroyed instance cannot be reused.

A call instance can be reused across multiple calls — a sequence of `join()`, `leave()`, `join()` works as expected. Only call `destroy()` when you are completely done with the instance and want to free all associated resources.

<Warning>
  Calling any method on a destroyed instance throws an `Error`.
</Warning>

## Return value

Returns `boolean`.

## Example

```javascript theme={null}
if (!call.isDestroyed()) {
  await call.destroy();
}
```
