Perhaps I interpreted the article differently, but I don't think it's about Javascript - it's about complex Javascript frameworks. Ie, ones that cause bloat via large dependency trees, and unnecessary computations. These aren't required for the interactivity you described.
I've written one of those React clones in Rust you mention. It was as you say - as much of a mess in practice as a JS framework.
