intentionally-fail-js-query	Intentionally fail a RunJS query

In this how-to guide, we will create a RunJS query that will throw an error.

Create a RunJS query and paste the code below. We will use the constructor ReferenceError since it is used to create a range error instance.
```
throw new ReferenceError('This is a reference error.');
```
Now, add a event handler to show an alert when the query fails. Save the query and Run it.

:::info Most common use-case for intentionally failing a query is debugging. :::
