Need to repeat the animation on the donor, how to copy it or understand and recreate it?

Question

JavaScript

I really don’t understand the canvas, there was no video that was easy to understand, but I would like to figure it out, specifically on this example or on a similar one.

Not just "learn, google" - so far it has not helped. I want to improve, but it is important to find how it will reach me in the best way.

Well, parsing snippets helps me, maybe someone used a similar one, or did it yourself?
Well, or in extreme cases - how to stupidly copy-paste it? where is the script handler for this background garbage with figures?

Answer 1

Sometimes just looking at the canvas element itself is enough
