Using immutable data structures provides many benefits, including making your code easier to reason about and less prone to bugs.

However, since JavaScript doesn’t include support for immutable data structures out of the box, you need to use a third party library. But which one to choose?

In this self-paced workshop, Immer’s creator Michel Westrate will guide you through the creation of a multi-user Gift Tracking app.

You’ll learn the basics of using Immer to handle immutable state updates, then go further into change distribution and implementing an undo/redo.

After this workshop, you’ll be ready to leverage immutable data structures in your own applications!
