Why are objects copied by reference in JavaScript (visualized)

This video is part of a series of online tutorials called 'JavaScript for Visual Learners'.
I will soon be uploading the first part of the video course in its entirety on this channel, as well as a free course on the Teachable platform, where there will also be interactive code examples. Please subscribe if you want to get notified when this becomes available.
This video will use visual examples to discuss:
-Why is copying an object different from copying a primitive in JavaScript?
-Why do we say that objects are copied by reference and primitives are copied by value?
-Why people learning JavaScript often find using the const keyword with objects confusing?
