Reselect is a small library that creates memoized selector functions for extracting and computing derived data from immutable state objects. It is commonly used with Redux but works with any plain JavaScript data structures.

Use cases

• derive computed data from Redux state efficiently
• prevent unnecessary recomputation of derived values in React components
• compose simple selectors into complex data selectors
• share reusable selector logic across multiple parts of an application
• optimize performance in large state trees by memoizing selector results

When to choose

• When you are using Redux or any immutable state and need memoized selectors to improve performance
• When you want composable, reusable selector functions that only recompute on input changes
• When you need a lightweight, TypeScript‑friendly library with strong community support

When to avoid

• If your project does not use Redux or similar immutable state management
• When selectors are trivial and memoization adds unnecessary complexity
• If you prefer a built‑in solution provided by another state library
