Yeah just to add-on to what other people are saying in replies, another happy mobx user. If I could guess at a complaint, I've worked on Ember projects (which have some similar observer / mutable capabilities) and have seen how "clever" observer / mutable-state code can turn out (overly complex). Which is to say -- it gives you some really awesome capabilities but no pre-set architecture for setting up your data modeling layer. At any rate, I really expect this library to take-off in the next year or two, and love introducing it to people who have not heard of it (normal response: "What? Whoa"). If you already have a lot of React experience, I think their 25-line timer example is a great place to see what it can do for you: https://jsfiddle.net/mweststrate/wgbe4guu/ https://jsfiddle.net/mweststrate/wgbe4guu/
