Class UndoStack<T>

The undo and redo stacks of steps (DOM-free): a new step clears the redo stack; at most maxSteps steps and maxCells cells (over both stacks) are kept – the oldest go first; a single step with more than maxCells cells empties the history and is not kept.

Example

const stack = new UndoStack<{ cellCount: number; label: string }>(100, 1_000_000);
stack.push({ cellCount: 1, label: "Edit" });
stack.undo()?.label;   // "Edit" – now on the redo stack
stack.canRedo();       // true
