Q: What problem does Redux solve?
A: Redux solves the problem of global state management and
"Prop Drilling". In large React applications, passing data
down through dozens of component layers becomes unmaintainable.
Redux centralizes the data into a single global store, allowing
any component to access the exact data it needs directly,
resulting in cleaner code and predictable state updates.
