reselect

Selectors only recompute when input arguments change, preventing expensive recalculations as shown in the basic usage example where memoized selectors skip runs.

Selectors can be nested and used as inputs to others, enabling complex derived state logic without performance loss, highlighted in the terminology section.

Returns the same object reference when inputs haven't changed, crucial for optimizing React and Redux re-renders, demonstrated in the example with equality checks.

Supports strategies like `lruMemoize` and `weakMapMemoize` for tailored caching, introduced in version 5.0.0 for flexibility.

Includes stability checks and output selector fields for debugging input selectors and result functions, aiding in identifying issues during development.
