React Fiber vs Svelte

Developers should learn React Fiber to build highly responsive applications, especially for complex UIs with animations, data fetching, or user interactions that require non-blocking updates meets use svelte for projects prioritizing fast load times and minimal runtime overhead, such as marketing sites or data-heavy applications where bundle size impacts user experience. Here's our take.
