Undo and redo operations are a must-have feature in any rich text editor – they’re a user's safety net. For a great user experience (UX), users need to solve their editing problems in a rich text editor.

An undo/redo button makes your users more confident, because it’s a clear signal that if they make a mistake, they can easily undo and restore changes. For example, if a user accidentally deletes a paragraph, the undo function can restore their work – and spare them a lot of frustration.

However, implementing the undo/redo functionality is complicated. It requires an understanding of data structures like Stack.

You need to know which actions need to be pushed onto the stack, as well as when to push them, and the same goes for the pop operation.

In this article, you'll find out about the complexity of creating and maintaining the undo/redo functionality, and see how the TinyMCE rich text editor makes it easy.
