This is _really_ cool. I don't know why a lot of commenters here are going into the weeds to grouse about Java, flash, and general anger at computational notebooks. What we have here is a complete client-side browser environment for development. Not some half-assed language or hyper restricted toy--this is real Python, and your browser's full JS engine all available in JupyterLab's IDE (basically a simpler VS Code at this point, it uses the same editing component). We all freaked out a bit as Apple drove out IDEs from their app store, Google locked down Termux and similar developer tools from Android. Well, here's the answer to those situations. Something no app store owner can kill on a whim. I love stuff like this and hope it helps to enable and inspire the next generation of developers.
