I've been using Svelte exclusively for the past 3 years or so. I love it and will keep using it as my main solution for interactivity. It's fast to use and execute, produces small apps, and it's extremely economical in how you express components.
The confusion the author expresses with $: reactive statements and store auto subscription with the $ are unwarranted IMO. It's really just a lack of familiarity but this kind of stuff becomes intuitive very quickly.
My criticism of Svelte is rather that they haven't gone deep enough into the compiler-based approach.
Would be great if there were something like .svelteStore files where you had all the automatic reactivity tracking without having to use a component. Or some kind of improvements into writing styles. With a compiler you can do anything you want and I think Svelte has been a bit timid, maybe to not scare people away.
For example Imba[1] also bet on a compiler-based approach (years before Svelte existed) and created their own language/framework/compiler. They have come up with amazing solutions to many problems. It's a shame they bet on Ruby aesthetics though and also that they aren't investing into marketing/docs.
Of course, one might argue that using a compiler is a bad idea for a number of reasons. And yeah of course there are objective issues to any approach, but you have to pick your poison. All in all, Svelte has made me tremendously productive compared to using other solutions for years (React, Vue, Mithril, Inferno, etc).
I will say though that I would rather use a solution that doesn't have any reactivity at all. Mithril and Imba have this concept of just "redrawing the whole thing" like a game GUI without having to worry about reactivity. Cognitively speaking, no reactivity is the best mental model IMO. With any reactive solution, it's very easy to fall into complex reactive dependencies which can be hard to track. The author of Imba has a video from 2018 where he talks about this[2].
Totally agree. I fully expect Svelte to start adding things like Nuxt 3's not requiring import statements for components. Hell, I could see in a couple years the script block allowing Rust with WebAssembly seamlessly generated but attribute binding logic looking exactly the same.
Compilers open up more avenues for productivity than most people in the web dev community realize.
