SVELTE helped me build a companion site CliqRex.com for our app! Svelte is the best javascript framework I've used to date. I like it better than VUE and React. :)
Super lean and reactive. No virtual DOM, super fast, and easy to write. Feels magical. Great DX, but still not as mature as React/Vue in the ecosystem.
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.
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!
