What is the future trajectory of React (React 20, Signals interop, and universal full-stack primitives)?

❓ Interview Prompt: Summarize future React innovations: React 20, React Compiler build-time memoization, TC39 Signals interop, and universal full-stack primitives.

React continues evolving into a universal full-stack runtime platform:

Key Technological Vectors:

1
React Compiler (React 19/20): Universal adoption of build-time auto-memoization, making 'useMemo'/'useCallback' obsolete.
2
TC39 Signals Interop: Potential fine-grained reactive primitives interoperating with proposed TC39 Signals standards.
3
Universal Full-Stack Primitives: Standardizing Server Components, Server Actions, and Streaming SSR across all meta-frameworks (Next.js, Remix/React Router, Expo).

Code Implementation Example

jsx
// Future React trajectory: Full-stack Server Actions + Auto-Memoizing Compiler!
export async function action(formData) {
  'use server';
  // Universal server mutation primitive
}

🎯 Interview Key Takeaway

React's roadmap centers on build-time auto-memoization, TC39 Signals interop, and universal full-stack primitives.
