Another way of stating it is that Svelte doesn't attempt to plug any of the leaky abstractions that already existed in JavaScript.

JavaScript is riddled with huge footguns that aren't even exotic use cases, and if you remove or paper over them, then it's not JavaScript any more.

While React's biggest most obvious leaky abstraction is that React isn't actually reactive.

Neither is Svelte, but at least Svelte doesn't have the audacity to falsly CLAIM it's reactive in ITS OWN NAME, like React does!

I do give Svelte credit for being quite self-referentially svelte, though! And that's something great that React definitely isn't.
