izure1/undoit

How izure1/undoit works

Undoit is a small TypeScript undo/redo library. Callers submit actions to synchronous or asynchronous history managers; actions invoke paired do/undo callbacks, and the managers maintain undo and redo stacks. StateHistory wraps the synchronous manager to provide push/undo/redo over a value. The README also documents the asynchronous busy-state capability. Edges reflect the supplied source excerpts and README; no external service or persistent store is involved.
