Testing Arcade

[FraserHand1]

Hi,

I'm skilling up on Arcade and trying to test some attribute rules.

I have this from here

https://developers.arcgis.com/arcade/function-reference/data_functions/#feature

But when I try to test this here

https://developers.arcgis.com/arcade/playground/

Is this an issue with the documentation or the sandpit app?

Is there anywhere else to test Arcade? Or more importantly test attribute rule expressions in ArcGIS Pro before saving?

Thanks

Fraser

EDIT:

Change the quotes and we get it working.
