Svelte 3: Rethinking Reactivity
I&#x27;m currently working on a giant React frontend codebase and it&#x27;s baffling how slow certain simple things are for our users. Yes it makes it easier for us to reason about, but performance should be able to scale without hacks.<p>Svelte seems to show a lot of promise, but I have a few things that I&#x27;m not 100% on.<p>1. How are the higher level abstractions for Svelte? Any framework can be easy for simple applications, but how easy will this be to reason about as we get to larger applications? React deals with this through a semi-functional mindset. What does Svelte offer?<p>2. Is there any plans for facilitating incremental rollouts? Changing your application to an entire new framework is not always worth it, and is greatly difficult. I could imagine Svelte being incredibly useful for large-scale, performant applications. However, unless it can be incrementally rolled out, then I can&#x27;t see how the biggest players will be able to utilise the power of Svelte.<p>I&#x27;d love to see the game changed in web frameworks, and I love the idea of using compilers where possible. If anyone could answer these queries, I&#x27;d be very much grateful.
