Can you make client script entry points asynchronous with the `async`/`await` keywords?

AI generated answer (using internal Slack threads):

In NetSuite SuiteScript, you cannot make client script entry points asynchronous with the `async`/`await` keywords. The reason is that NetSuite's client-side scripting environment does not support asynchronous operations in the same way that a typical browser environment does. In the context of SuiteScript, the `async`/`await` keywords can be used, but they will still run synchronously. This is because the SuiteScript engine does not support true asynchronous operations. In the provided conversations, there is a suggestion to use one of the promise-based methods like

PagedData.fetch.promise

if you want to work asynchronously. However, this is not the same as making the entire client script entry point asynchronous. Also, it's important to note that when you try to upload a SuiteScript 2.1 ClientScript file using async entry point functions, you might encounter a validation error stating

SuiteScript 2.1 entry point scripts must implement one script type function.

This is because the NetSuite environment expects specific entry point functions for different script types, and these cannot be asynchronous. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
