Svelte has been around for quite a while now. It's pretty lightweight, fast, concise, and is essentially a compiler, which means there is no virtual DOM and all the other unnecessary stuff.
As far as I have played around in the sandbox mode, it felt like it would be an awesome tool for smaller apps to get you up and running quickly.
.svelte files reminded me of the good old classic design we used decades ago, while still using components.
Have you built any projects with Svelte and did you like it?
