A huge week for both Svelte and Next.js
#710 — October 24, 2024
JavaScript Weekly
Svelte 5 is Alive — The long awaited next major release of Svelte, the compiler-driven JS UI framework, is the “most significant release in the project’s history”, while remaining largely backwards compatible. A big addition is runes for explicitly declaring reactive state, but there’s much more besides. The official svelte.dev site has also undergone a big rebuild to act as an ‘omnisite’ for all things Svelte.
