Following up from my article about XState and Stately.ai, fellow reader S. asked if `useReducer` could ever be relevant when using state machines in React code. Yes! Here's how

Two years ago I wrote about using XState after building a UI interaction so twisted my brain leaked out my ears. It helped. Now the creators have made something even better – Stately.ai 😍

When you grok state machines, a new world of computational beauty and software design opens in front of your eyes. Things that used to be hard become easy. The impossible becomes possible. And you turn into that annoying team member.

Every null or undefined check doubles the number of tests you need 😱

Support for Firebase Auth is one of the most requested features for useAuth and I figured what the heck, how hard can it be?

useAuth works without React Context! 🎉 here's how

In Refactoring a useReducer to XState we talked about a 5 step process to turn a reducer into an XState state machine. Today answers "Ok now what?"

Once you know how to refactor a useReducer to XState, you gotta prove you did it right.

XState promises to be like useReducer+Context combined and the simplest way to handle complex state in React apps. But can it deliver? On this episode of #CodeWithSwiz, we gave it a shot.
