One of my favorite math/graphics YouTube creators Freya Holmér did an excellent intro to Geometric Algebra not that long ago [1]. If you have any interest in 3d graphics (especially but no limited to splines/Bezier curves) then be sure to check out all of their videos.

I personally have always struggled with linear algebra and I tend to find these Clifford Algebra approaches much more intuitive.

What a wonderful talk, thanks. It reminded me of https://enkimute.github.io/ganja.js/ which is actually a library by enkimute, the OP! (It's quite a remarkable library too, by being a single file, no-build script that supports N dimensional algebras along with render support.)
This is who I thought this was going to be. I enjoyed this along with the Splines & Beziers ones. Such great presentation, never feels rushed but gets to the point.
the splines yt video (https://www.youtube.com/watch?v=jvPPXbo87ds) is (IMHO) one of the best educational videos on a programming topic, full stop.
I knew the name looked familiar. Splines was a fantastic video.
I'd like to point out that the YT comments have some good (weird for YT, I know!) clarifications and questions about bits where she did go a bit fast or skip over things, e.g. the non-commutativity of products (in general) and such.

Great video.

Thank you for sharing, I really enjoyed her talk.
I never thought maths was that cool.
