In this episode Donn talks about why you need to learn React (or Flutter) - so you can truly understand the Unidirectional data flow pattern in a framework that was built for that purpose alone.Working with other frameworks which bolt on a custom unidirectional data flow is often hard to understand. When you work with React and learn how it works, the concept of Unidirectional data flow starts to make much more sense as that is the default way to implement UI's in technologies like React (and Flutter).This exposes you to the pattern and helps you understand it. In turn, this will help you become a better developer.Show NotesUnidirectional Data flow ImageHow to learn React:Tyler McGinnis Course on React (this is how I learned it)Tyler McGinnis React Hooks CourseHow to Learn FlutterRohan Taneja's Flutter from Zero to Hero Course (Free)Flutter Crash CourseDonn's Free E-Book on Freelancing RatesFree E-Book on Freelancing RatesContact@fragmentedcast or our Youtube channel@donnfelker and donnfelker (on Instagram)Freelancing for Mobile Developers (Donn's YouTube)kaushikgopal (on YouTube) or blog.kaush.co or @kaushikgopalDisclaimer: Many of the links we share to products are affiliate links.
