Indeed. You can get all the main benefits of two-way binding in a one-way dataflow system like React by using cursors... i.e. whenever you access a property `state.foo.bar`, also derive the setter/updater, `setBar(…)`.

With proper memoization, this is both fast and ergonomic, and it even allows you to turn mutations into data and pass them to a server. I've implemented this as a stand-alone state helper [1] based on JSON patch/diff, and it's magical. Undo/redo, multiplayer, it's all within reach.
