I'm confused by all of these MVetc... libraries. We had routing behavior to content/views covered already. How is anything that does more than help isolate/manage data more than cruft in regards to having some sort of MVC-but-not-really-style-app on the client-side-web? IMO, it's all just pointless abstraction of the type that JS devs should have learned to avoid from observing server-side fail over the years. What really blows my mind is the number of these frameworks that embed pointless behavior dependencies directly in the HTML and act like they're doing us a favor. That's awesome, now we're back to changing things in multiple places to make adjustments to our apps that used to happen in one place following basic "duh" best practices that the authors of these frameworks don't appear to have ever understood properly. HTML is the router you saps! Hell, how about we add pointless-in-a-language-with-first-class-function IOC fail, config files and pointless dependency management as well? Wait WHAT!? ARE YOU !@#$ING SERIOUS!?
