What's new in Svelte 5

What this post added

This post details the technical advancements in Svelte 5, focusing on the introduction of 'runes' ($state, $derived, $effect) for explicit and fine-grained reactivity, replacing older syntax. It highlights the shift towards universal reactivity with .svelte.js files for shared state and logic. Compiler improvements are discussed, including components as plain JavaScript functions for better optimization and native TypeScript support. The introduction of 'snippets' as reusable markup and logic blocks, replacing slots, is also covered. The post also touches upon the benefits of Vite integration within SvelteKit for development tools and performance.
