I'm really looking forward to React 19. It'll be nice to revisit after spending so long with Next JS

I was reading about this the other day. Apparently using subsequent commas in an array is a method for omitting array indices. In different contexts, this method's omitted values will sometimes be read as undefined.

Great video Brad. Thanks for making and sharing it. Are you planning to update the react course on your website?

Minor thing, 13:09: Regardless of the use() hook, you wouldn't have to `return await res.json()`. (Unless you're using a try/catch)
