To further this point, don't use any library you don't need. Don't pull in Reselect until you need it (and you don't need it), Redux once you're big enough and you're passing a doTheThing() callback prop down 3+ hierarchy levels. The only "best practise" for starting is doing less, then re-evaluate when your app has too many complexities (which is the only thing more libraries will create, or solve)
