How to calculate intersected areas in Arcade?

Two questions I suppose - is it possible to calculate the overlapping areas of two separate polygon layers in Arcade? And if so, how?


I have two layers - land blocks and survey areas. For each of the survey areas, I want to know what area of it intersects/overlaps with the blocks. It might be completely within a block, completely outside a block, or partially intersecting. If I was doing this via geoprocessing in Pro, I'd probably use the Summarize Within tool. However I'm looking for an equivalent in ArcGIS Online that calculates the overlapping areas into a field within the survey areas layer.


I've been looking at the Intersection Arcade function, but struggling and can't find any examples of Intersection in use (it's all Intersects).
