> While Svelte uses a (tiny) bit of custom syntax, React makes you bring in a ton of DSLs. Hooks, the component lifecycle, and all the third party libraries you will need to build a functional app require a lot more effort. People forget just how much stuff they had to learn. I don't disagree with this, but people unfairly complain about it anyway, and it's another roadblock in the adoption process that makes it less exciting to fight for. > and nested components hundred-levels deep, and you start noticing slowness, performance optimization is a gigantic effort. That right there is the problem. The DOM is optimized for something like 32 levels of depth which is also the standard used for lighthouse scores. It's always possible to go over that, a little bit, but hundreds? At that point, it's not a question of svelte vs react, but really advanced dom (if even that) manipulation.
