For JS and Typescript there’s Quokka, which I haven’t tried and doesn’t really seem to be in the style of a notebook, but might be helpful? https://quokkajs.com

For JS and Typescript there’s Quokka, which I haven’t tried and doesn’t really seem to be in the style of a notebook, but might be helpful? https://quokkajs.com/ https://quokkajs.com/ There is actually a JS adaptor/extension for Jupyter but I found it pretty clunky to use, and since I’m equally comfortable with Python as JS, I just stuck with Python. For Typescript Stackblitz might be interesting, but it’s not like a notebook, and it’s not a run-locally tool.
