I got up and running in Svelte in literally 5 minutes, and it blew me away. I just started building and referencing the docs along the way. But then...I ran into their reactive model, and spent an entire day trying to debug (what I thought was) a very simple problem. I can't recall the details but I remember it had something to do with the order of updates? It was super confusing. Moral of the story is that there are always trade-offs.
