What Does Redux Do? (and when should you use it?)

Great article from Dave, as always.

Worth noting that this is primarily about how Redux works with data flow in a React app, and doesn't go further into its other benefits, like predictability and debugging. I wrote some similar thoughts in a post I co-wrote for Full Stack React on why Redux is useful in a React app [0]. The Redux FAQ also helps answer "when should I use Redux?" [1].

For those looking to learn Redux, start with the official docs [2] and Dan Abramov's videos on Egghead [3]. My React/Redux links list [4] has an extensive list of additional tutorials and info.

For anyone who has read this post, I highly recommend you read through the comments--in my opinion the author has missed the point of Redux completely (at the time I am writing this reply), and there's a key thread in the comments section that tries to set things straight.
