Undo/redo functionality isn't just for text editors, it's critical for rich apps like form builders and design tools.To build a fully working persistent undo/redo stack in React, you can use hooks and context without relying on Redux or Zustand.The first step is to create an undo context that tracks a history of states and provides undo/redo functions.Next, build an editable component that records its history, and add undo/redo buttons to control the undo/redo functionality from anywhere in the app.
