That's just React, which both has the highest market share and a culture of following the latest fad combined with piecing together applications from multiple tiny modules(because "it's a library not a framework").

Also jQuery becomes slow and unmaintainable very fast, especially considering that modern frameworks do a lot of tricks to increase performance, like detecting a row swap in a list.

Next gen frameworks like Svelte and SolidJS managed to avoid some of that because they compile to a minimal, Vanilla JS app which is easy to read. Especially Svelte at least gives you a decent stack trace.
