Predictability, immutability, single source of truth — these are all concepts that are absolutely essential to understand in order to have reasonable, straightforward state management in your frontend applications. Unfortunately, implementing these practices isn’t always so straightforward.

You may have heard of callback hell, or even async/await hell, but are you also stuck inside of spread hell? Developers often find themselves in spread hell when every update to their state means drilling down multiple levels to change some value, and then spreading objects all the way back to ensure immutability. At the least it’s ugly, and at the worst it’s a difficult to debug, complicated headache.

What if you could save yourself the headache by simply mutating your state? In this talk, we will explore a tiny, yet powerful library that will save you time while resulting in cleaner code, more straightforward state management, and even in some cases, better performance.
