### Remarks

The **cache** object is useful when you need to store information between multiple script executions.

Recall, your scripts will run when a supported action (event) occurs. After your script completes, it will not run again until another supported action occurs. If you want to store information from one execution and retrieve it on subsequent executions, this object provides a way for you to do so.
