There are some great things going on in React &#x2F; Flux, but the part that needs to be emphasized about Flux, that Facebook doesn&#x27;t address explicitly anywhere, and that most people eager to always be on the cutting edge will never admit, is that this stuff was designed to solve problems for <i>very</i> complex applications. Complexity is relative, and the solutions that reduce complexity and friction in the development process for Facebook may increase it for another organization. That is to say, Flux &#x2F; React et al is by no means simple. Not even a little bit. But it probably simplified <i></i>a lot<i></i> of things for the Facebook team. However, YMMV for your 6 person startup engineering team.
