Which of the following is NOT a fact about workflow action scripts?

Workflow action scripts are indeed synonymous with custom workflow actions, which means they are utilized to extend the functionality of workflows by incorporating custom logic. By leveraging these scripts, developers can implement additional automation capabilities that are not possible through standard actions within workflows. This allows for a more tailored approach to automation that can handle complex use cases effectively.

When it comes to their functionality, workflow action scripts are designed to utilize JavaScript as part of the SuiteScript API, enabling developers to execute various operations and computations. This integration allows the scripts to perform complex computations, interact with records, and manipulate data as necessary, thereby maximizing their potential in workflow automation.

Given this understanding, the assertion that workflow action scripts cannot use JavaScript is incorrect. The ability to use JavaScript is a fundamental aspect of these scripts, enabling their full utilization within workflows to create custom actions tailored to specific needs.
