"Official" LODs

Hi,

The task is to restrict user to go to zoom out.

I wondering if ESRI has "official" zoom level/resolution/scale defined in some documentation. I understand - LODs are settings (could be changed). But what are "out-of-the-box" LODs settings?

 

The official help provides only 5 levels (are they the same as for default map (if we do not put LOD in Map constructor))

Map (legacy) | API Reference | ArcGIS API for JavaScript 3.18 

 

I found also How can you tell what map scales are shown for online maps? | ArcGIS Blog
