It's a data science package from the looks of it, and I, as a data science person would be interested. But then, Javascript? I only know Python, and my Notebooks are sort of similar to this, but in Jupyter-lab I have Pandas and Seaborn (among many others, and I can access any file, any api, any database). If those were available I might have tried it, although my Jupyter-lab notebooks also make nice PDF reports, the only difference I see is that you can place cells next to each other, right? Maybe there is an extension for Jupyter-lab that can do that. So what is the USP? Javascript? Just Ducking around I found I can also do that in Jupyter-lab: [0] [0] http://bluegalaxy.info/codewalk/2017/12/04/javascript-how-to-install-javascript-kernel-in-jupyter-notebook/ http://bluegalaxy.info/codewalk/2017/12/04/javascript-how-to...
