Xanadu ES12 in Global

[NS]

Hello,

The Xanadu highlights in docs state:

• Use ECMAScript 2021 (ES12) features in any server-side script.

I understand this to also mean Global scope, in scoped apps this has been available since Tokyo. I spun up a PDI which is running on build `glide-xanadu-07-02-2024__patch0-07-16-2024`

Apart from `const` and `let` no new ES features seem to be working. I was trying template literals, for...of loop, arrow function and spread operator. I tried running both in a Fix Script so I could make sure the ES12 toggle was on, and in background script. But the result isn't good.

Script compilation error: Script Identifier: null.null.script, Error Description: syntax error (null.null.script; line 4), Script ES Level: 0, Interpreted Mode: true

bg script 

fix script 

In a scoped app the same script runs like a charm

The docs also state "No plugins or properties are required to install the new JavaScript engine."  So what gives? Any ideas?

edit: maybe this post went into a wrong category - idk how to change it though

Got reply from SN:

Thank you for your patience on this. At this stage, we could see that the Defect has been waived for Yokohama and Targeted to Zurich. 

Will keep you posted as soon as the fix is available.

ServiceNow finally acknowledged that the feature indeed does not work:

KB1699139 + Related Problem: PRB1794568

https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1699139

No info on when it'll be fixed though.

I tested it both ways, it was just easier to take a screenshot that way so that it would show all relevant elements.

But I can't say that I agree with the comment about the background scripts, because of the way they've put it in the release note highlights: "Use ECMAScript 2021 (ES12) features in any server-side script."

It'll be interesting to see when SN gets back to me regarding this topic. In the past I haven't bothered looking into early availability versions, so I wonder how many of the bugs are still present on actual launch?

Just tested this in a newer version `glide-xanadu-07-02-2024__patch1-08-24-2024`, ES12 mode is still not working in global scope

Script compilation error: Script Identifier: <refname>, Error Description: destructuring assignment is an ECMAScript 6 feature - not supported (<refname>; line 12), Script ES Level: 0, Interpreted Mode: true
Javascript compiler exception: destructuring assignment is an ECMAScript 6 feature - not supported (<refname>; line 12) in:

And got confirmation from SN support that it this indeed is broken still - not just for me.
