What is Svelte Advanced
Svelte is a JavaScript framework that compiles components to vanilla JavaScript at build time, eliminating the runtime overhead of frameworks like React and Vue. Advanced Svelte includes reactive assignments, stores (state management), transitions/animations, and component composition patterns. The key innovation: Svelte moves work from runtime to build time. Instead of React's virtual DOM diffing at runtime, Svelte's compiler knows exactly which variables are reactive and generates optimized update code.
