Can useEffect affect your codebase negatively? From fetching data to fighting with imperative APIs, side effects are one of the biggest sources of frustration in web app development. And let’s be honest, putting everything in useEffect hooks doesn’t help much. In this talk, we'll demystify the useEffect hook and get a better understanding of when (and when not) to use it, as well as discover how declarative effects can make effect management more maintainable in even the most complex React apps.

Over the past few years, state machines, statecharts, and the actor model have proven to be viable concepts for building complex application logic in a clear, visual way with XState. In this talk, we'll take a peek into the future of XState, including new features in the next version, and new tools and services that will make it even easier to create and collaborate on state machines.

Learn about state modeling with state machines and statecharts can improve the way you develop application logic, and get a sneak peek of never-before-seen upcoming visual tools that will take state management to the next level.
