A new major version of Svelte svelte@5 has been released! 🎉

The new version brings:

• even better performance,
• a more granular reactivity system with runes,
• more expressive template syntax with snippets and event attributes,
• native TypeScript support,
• and backwards compatibility with the previous syntax!

More details can be found on Svelte's GitHub page..

A great introduction to the new syntax is published here.

React developers may find the new Svelte 5 syntax quite familiar, as compared here. However, the underlying mechanisms are, of course, quite different.
