Basically this is markup + code (Javascript), which is a combination targeted by MDX. The last time someone mentioned this, the author said Nota is geared towards documentation, while MDX is geared towards web sites: https://news.ycombinator.com/item?id=31349579

If that is so, I think someone needs to wrap Nota into a product for it to take off. Because while the results look great, fiddling with node.js to build a document is too much work -- it's like Latex all over again. Most people will prefer to use Notion or a word processor.
