What is React Navigation and how does it work internally?
Updated May 6, 2026
Short answer
React Navigation manages screen transitions using a navigation state tree.
Deep explanation
React Navigation maintains a navigation state that tracks routes, history, and params. It uses a JavaScript-based routing system and integrates with native navigation primitives. Each navigator (stack, tab, drawer) maintains its own state and can be nested.
Real-world example
E-commerce apps switching between product list and product details screens.
Common mistakes
- Creating deeply nested navigators without structure.
