💡 Real-world example: A <Select> component should manage its own internal state but expose selection via onChange .
Shared across multiple non-hierarchical components (e.g., user authentication, theme settings).

Essential for SEO-heavy sites (Next.js).
Divide your JavaScript bundles by route or component using dynamic imports to ensure users only download code relevant to their current view.
If you are preparing for a Frontend System Design interview—a standard requirement for Senior, Staff, and Principal Engineer roles—you can use the structured approach taught in elite curriculums: State Management Strategy Allows updating static pages in
"Learn the concepts, not the frameworks. The frameworks change every 18 months, but the laws of HTTP, browser rendering, and human psychology remain constant."
The HTML is generated at build time. Incremental Static Regeneration (ISR) allows static pages to be updated in the background as traffic comes in, combining the speed of static sites with the dynamic nature of SSR. Critical Performance Metrics & Core Web Vitals
Keep state as local as possible. Move it to a global store (like Redux, Zustand, or MobX) only when multiple non-adjacent components need access.
Choosing how and where code turns into HTML is critical for SEO and performance:
Define functional requirements (features) and non-functional requirements (scalability, offline support, target devices, latency constraints).
