Synchronized Updates: Consistent UI updates during async operations
Performance Patterns: Avoid waterfalls, optimize concurrent requests

⚡ Remote Functions

Type-safe Communication: Full TypeScript support between client and server
Four Function Types: Query (read), Form (submit), Command (execute), Prerender (static)
Optimistic Updates: Immediate UI feedback with server synchronization
Progressive Enhancement: Works with and without JavaScript

📚 Comprehensive Documentation

Real-world Examples: Patterns from core maintainer projects
Migration Guidance: Step-by-step Svelte 4 to 5 migration
