EntityHelpers

Lets scripts identify entity helpers through the EntityHelpers global,
without knowing their Java package names.
Checks follow helper inheritance, not entity registry IDs. These are Java types,
so their existing constructors and static members are also available. The group members are read-only. Listing a type here does not change which helper a factory returns.

const entities = World.getEntities();  
if (entities !== null) {
 for (const ent of entities) {
   if (ent instanceof EntityHelpers.Horse) {
     Chat.log(ent.getVariant());  
   }
 }
}

These names are available in JavaScript and Python without importing anything. They are read-only aliases of Java types, so instanceof works as usual.
