What is State Management?

State management refers to handling application data that changes over time. For complex apps, solutions like Redux, Zustand, or React Query help manage global state, server state, and derived state efficiently.

Why is it Important?

As applications grow, managing state becomes complex. Understanding when to use local vs. global state, and choosing appropriate tools, is crucial for maintainable applications. Poor state management leads to bugs and performance issues.

What to Learn

• Local vs. global state
• React Context and useReducer
• Redux and Redux Toolkit
• Zustand or Jotai
• Server state (React Query, SWR)
• State normalization

Career Relevance

Senior frontend roles require state management expertise. Understanding different approaches and when to use each demonstrates architectural thinking valued by employers.
