My overall takeaway is that a lot of where I thought React was going initially was stuff I see present in Elm, and that Elm had pinned down since seemingly before React got on the scene. Namely, I am thinking of the observer pattern style way of updating data.
I haven’t written anything in React in several years, nor have I had a customer ask for it. PHP, Go, and Python. I have colleagues using Elixir, Python, Ruby, but no React.
As an example, Adobe recently brought Photoshop to the web browser with these two technologies, which seems unthinkable with React.
Before that I used Vue, which was more tolerable.
