Problem Statement
What are the most common Redux anti-patterns and how do you avoid them?
Explanation
Common anti-patterns include mutating state directly which breaks immutability and causes bugs, putting too much state in Redux including local UI state that doesn't need sharing, creating deeply nested state structures that make updates complex, dispatching actions in reducers which breaks the unidirectional flow, and storing non-serializable values like functions or class instances in state. Avoid these by using RTK's Immer integration for safe updates, keeping local state in components with useState, normalizing state structure, using middleware for side effects, and only storing serializable data. Other mistakes include creating selectors inside components causing performance issues, not using action creators consistently, and over-fetching data instead of lazy loading.
