Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

TLDR: The cascade={"remove"}
is like a "software" onDelete="CASCADE"
, and will remove objects from the database only when an explicit call to $em->remove()
occurs. Thus, it could result in more than one object being deleted. orphanRemoval
can remove objects from the database even if there was no explicit call to ->remove()
.
