Svelte RFC 0001: Reactive assignments (via) Svelte is a really interesting JavaScript framework: it offers a similar component-based developer experience to React but does it while delivering a tiny amount of code-to-the-browser thanks to being built entirely around a compiler that generates the minimum code necessary. In this RFC the Svelte team propose taking this approach even further, by generating code to accompany every relevant variable assignment that can trigger the corresponding view update. The document also has a very clear explanation of how React, Vue and current Svelte differ in their solutions to the challenge of updating the visible HTML view when the corresponding state changes.
