Hi Rich, I notice you mention Marko. That was my first thought when checking out Svelte today - Marko uses somewhat similar approach, and thus brings somewhat similar benefits. But Marko has couple of other advantages - beautiful "concise" syntax option, and easy debugging at dev time as the Lasso bundler turns JS modules into equivalent files in the browser, complete with same line numbering. (It only works with CommonJS modules, but that's what I prefer to use anyway as it allows unit testing in Node without transpilation.) What advantages would you say Svelte has that would make me consider using it over Marko? Thanks.

I'd say it's a matter of personal preference as much as anything else. (Personally I'm not a fan of the compact syntax — I prefer just using HTML and CSS, but it's subjective.) Performance-wise, you'll get great results with either framework. You mention debugging — Svelte creates useful sourcemaps, and the generated code is very readable anyway. Svelte has a few features you might find interesting (AFAIK Marko doesn't offer these, though I'm not intimately familiar with it): * it can compile directly to custom elements * your styles are scoped to the component * declarative transitions * built-in global store (think Redux, but zero boilerplate) * useful element bindings (for e.g. customisable media players https://svelte.technology/repl?example=binding-media-elements https://svelte.technology/repl?example=binding-media-element...) * computed properties. these are a lifesaver when you're doing a lot of complex reactive stuff and so on. Also, I don't think Marko has an equivalent of Sapper. Finally, while Marko is slimmer than the likes or React or Vue, there's still a runtime library you need to include on your pages. A typical Sapper page is about the same size as Marko by itself, before you've added any app code.

  Thanks, sounds worth a closer look.
