The developer experience is second to none. State just works, the performance is wild, and deployment options are diverse. I definitely see Svelte becoming one of the biggest web frameworks in coming years.
I'm building everything with it these days and whenever I have a pain point, a quick search reveals that there is an elegant solution already baked into the framework itself. Just top-notch modern web!
Svelte is easier than the others, faster than the others and compiles to a single lightweight and efficient javascript file. Svelte is free of virtual dom, heavy libraries, slow performace and complicated verbose code. I love it!
