great! i like it, thank u for this update.
bttw, how did you put cursor effect when u are in vscode? that's look amazing

[@emmanueldalougou7727]

thanks to you. by your tutorial i have fixed my flashing optimistic state in my nextapp. every time i got the old state. you're genius

[@Archheret1c]

Good video, but with a hook like useOptimistic it would be nice with an example when the optimism was unwarranted aka failed to update (error).

[@user-ik7rp8qz5g]

I am more curious about release date of stable 19 version to finally use it in prod. Any info on this?

[@IAmMrAcid]

I'm using NextJS v14 for production and they already had all the experimental features from React v19. Things look good, no issue at all.
