Solves what problem? The article is about some very minor syntax sugar, while you are plugging a tangentially related library with a whole raft of its own abstractions. I’m struggling to understand the context here.
Suggesting RxJS in this context IMO is like when someone suggests doing `const $ = sel => [...document.querySelectorAll(sel)];` as helpful syntax sugar for the 20-lines of JS project but they get shut down because it's no React.
