Svelte allows isomorphic rendering (client & server side). Svelte also has a feature called rehydrate, which will bind the component to html rendered on the server side; sortof like serializing/unserializing.

This enables me to use Svelte for both client-side & server side rendering, replacing other template systems & having the best of both worlds (page caching, dynamic behavior on the client, a scalable front-end architecture, composition, etc).
