Debouncing is a known development tool for most non-immediate actions. It's related UI concept of locking individual UI elements is also well understood by many users (not by that technical name, but by "it's working on my action" kind of understanding).

I don't particularly like React, but this a core feature of such JS frontend frameworks, optimistically "succeed" while async network and back-end work happens to give the illusion of speed: https://react.dev/blog/2024/04/25/react-19#new-hook-optimist...

Is this an LLM? :) The question was rhetorical. Both of these proposals have problems. But the main issue is that the author of the article is missing an angle of toasts as a UX concept.

From my perspective there was nothing rhetorical about that question as I occasionally encounter it as a serious thing. Some colleagues really do not want optimistic UI events. Some swear by them.

I don’t have any strong feelings one way or another as long as there is proper inline feedback.
