In fact I use Jupyter almost exclusively for Sage, though too infrequently to get a subscription to CoCalc. Incidentally it isn't clear to me how I can get the Sage kernel into another installation of Jupyter, or other kernels into the Jupyter installation embedded in sageMath. If I used Jupyter instead of R/RStudio or Julia/Juno the draw would be having the different toolsets and their environments all accessible in one primary interface.
