Svelte vs React: An Unpopular Opinion

This will upset some people. That's fine.

React is the dominant frontend framework. If you want to be employable as a frontend developer, you learn React. But here's my unpopular opinion: Svelte is a genuinely better framework for building things.

The Reactivity Problem

React's mental model requires you to constantly think about what causes re-renders, what needs to be memoized, why your useEffect is firing. Svelte's model: "this variable changed, update the DOM node." That's it.

// Svelte — just works
let count = 0
$: doubled = count * 2

// React
const [count, setCount] = useState(0)
const doubled = useMemo(() => count * 2, [count])

Bundle Size

Svelte compiles to vanilla JavaScript. A Svelte app ships less JS than a React "Hello World." For performance-sensitive apps, this matters enormously.

My Conclusion

Use React when you need to. Use Svelte when you can. The web is better when we have real alternatives.
