what do people make with this?

VIBE 1

Cache selector results per argument so filtering or grouping data across components stays fast.

VIBE 2

Swap Reselect for re-reselect in an existing Redux app with minimal code changes.

VIBE 3

Avoid recomputing expensive data transformations when a selector is called repeatedly with the same arguments.

VIBE 4

Limit how many cached selectors are stored to control memory usage in a large app.
