I've been programming professionally for over 22 years and writing code since I was a kid (over 30 years). My number 1 lesson is... You will never know everything there is to know about programming so keep learning and don't stress. Other useful lessons... Good code works well consistently and is easy to change . Only invest in changes to existing code that enhance one of those two properties. Everything else is a needless distraction. Every bug is fundamentally the result of an invalid assumption. Strive to discover and convert as many assumptions to assertions as possible. This applies both to your actual code and also to your interactions with clients, product managers, business domain experts, etc... Never leave a bug until you truly understand what caused it. You should be able to recreate and fix it at will. In other words ... Write code that is kind to the poor schmuck who'll have to change it later, because often that schmuck is you. – Bill (from DevMastery )

To learn React (for free), you can start with this tutorial: http://courses.reactjsprogram.com/courses/reactjsfundamentals The best video for learning React-Redux that I have seen is from Wes Bos. It assumes you already know React. It's free and you can check it out at: http://wesbos.com/learn-redux/ Wes also has a React online course, but it is NOT free. If you find yourself struggling with his Redux course, it may be worth checking out his React course first, and then coming back. After you've taken the Wes Bos Redux course, you should check out the free course by Dan Abramov (the creator of Redux). You can find it at: https://egghead.io/courses/getting-started-with-redux . It's a bit more advanced than Wes' course because it goes into detail about how Redux works under the hood. Has some very valuable insights. Next, check out Dan's follow-up course on building React applications with Redux at https://egghead.io/courses/building-react-applications-with-idiomatic-redux Finally, play around with some seed projects and boilerplates. One that I like is React-Boilerplate which you can find at: http://reactboilerplate.com Then, you should be all set to go. Hope that helps. Best Regards, Bill (from DevMastery )
