I still don't get buffers - programming.dev

any emacs elitists here?

I’m just an emacs … enjoyer (…?) and I just don’t understand the post. I’m pretty sure buffers here refer to something different from emacs buffers as they’re completely unrelated to clipboards. Then from a quick scan of the plug-in mentioned it seems to mimic the clipboard ring emacs has had for many decades (always?).

Basically I have no idea what’s going on here.
