redux‑undo is a tiny higher‑order reducer for Redux that adds built‑in undo/redo (and jump/clear) capabilities to any slice of your store. By wrapping an existing reducer with `undoable`, developers get a history object (`past`, `present`, `future`) and a set of action creators to move through it, making it ideal for UI‑heavy apps such as editors, drawing tools, or any application that needs user‑driven state rollback.
