I find it very confusing why they don't embrace the JavaScript echo system. I'm all for a new syntax that does away with some of the bad parts but if you can't async/await, well then you can't really do I/O, and if you can't do that then your app isn't particular fun to use.

That said, I get that there's callbacks for everything and that you can do I/O with callbacks but it's not fun and if that is your only option you're going to need some external Flux "store" to manage all your state.

Edit: I should also add that I understand that there are people who find the async/await paradigm to be bad but I don't think we have much of an alternative when it comes to JavaScript or if you want an alternative, we'll then you are hardcore enough to be fine with just callbacks.
