VS Code: Debugging with Jest

VS Code: Debugging Jest

Sometimes, debugging with console.log is not enough to find out what is happening in the code, as console.log prints only plain objects but neither functions nor objects with circular references. Besides, it's possible you may need to know the context and flow of the code.

What's the difference between cascade="remove" and orphanRemoval=true in Doctrine 2

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().

I answered this question a few times to different people so I will try to sum things up in this Gist.

Let's take two entities A and B as an example. I will use a OneToOne relationship in this example but it works exactly the same with OneToMany relationships.
