Jupyter started from ipython, originally mostly written in python and for python. But the project was so successful that it extended for other languages using cell magic and then kernel system. The team is now mostly using JavaScript, Typescript, except for ipython sub-project. Although it's obvious choice for schools, research, analytical work, and publications, still I really wish for more adoption in corporate environment, that got stuck in proprietary tools.
