FWIW I agree with you. I’ve been thinking for a while Phoenix could provide a sort of standard library for common JS functions. Another big one is updating whatever structure is tracking changes on the front end. Perhaps declaring default values and types like attrs in components but they can be manipulated by JS functions client side (with all the code written in LiveView/Elixir/Plug style). A use case for this is optimistic renders on form submissions.
My point with the comment above is more so for people interested in CSS that have yet to be exposed to modern capabilities
