Svelte vs. Vue performance comparison

When it comes to performance, Svelte outperforms Vue due to its compiler-based approach. Unlike Vue, which runs in the browser and relies on a virtual DOM, Svelte compiles components at build time, eliminating runtime overhead. This makes Svelte applications faster, with smaller bundle sizes and reduced memory usage.

Vue, especially with Vue 3's reactivity system and tree-shaking optimizations, offers great performance but still incurs some runtime processing costs. If you need lightweight, high-speed UI updates, Svelte is the better choice. However, Vue remains strong for scalable, component-heavy applications.

Key Takeaways:

• Svelte → No virtual DOM, faster execution, and smaller bundles.

• Vue → Optimized reactivity system, but has some runtime overhead.

• Svelte is better for performance-critical applications, while Vue scales well for complex UIs.
