A comprehensive comparison between React and Svelte 5 covering state management, component lifecycle, styling, event handling, and form inputs. The guide demonstrates how Svelte's new runes syntax simplifies reactivity with compile-time optimizations, while React relies on hooks and runtime updates. Key differences include Svelte's built-in two-way binding, scoped styling by default, and more concise syntax for common patterns like conditional rendering and component communication.

From React to Svelte 5 — a practical comparison

I’ve recorded a short walkthrough that rebuilds a handful of everyday React patterns in Svelte 5. It isn’t a benchmark or a framework “debate”; it’s a side-by-side look at how common tasks feel in code.

In the video you’ll see:

Declaring and updating state (useState / $state)

Computed values (useMemo / $derived)

Scoped styles and minimal templates

Basic loops, conditional blocks, and event handling

Lifecycle cleanup (useEffect cleanup / $effect return)

A quick note on component composition (props, slots, context)

The goal is to give you a clear sense of Svelte 5’s new runes syntax and where it might simplify day-to-day work compared to React’s hooks. If you’re curious about Svelte but prefer seeing real code rather than reading feature lists, this should help.
