apparently now you can run Jupyter notebooks in the browser without a server with WebAssembly using JupyterLite?? https://jupyterlite.readthedocs.io/en/stable/

I learned about this because @paddymul made a pull request to my pandas-cookbook tutorial on github to add support for it

you can try it out here, it seems to work: https://jvns.github.io/pandas-cookbook/lab/index.html
