I hate to sound curmudgeonly, but the reason the state of JS is always in flux is because app developers suddenly decide they want to do front end development, and they come in and say, "WTF, everything here is weird and broken. I'm going to fix it. Make it more like python/ruby/.NET/C++/LISP/Haskell/Objective-C". So then some high brand developer heads up a project, it gets a lot of attention because a big name company adopts it, and then we're off to the races. Before you know it, our simple little dynamic prototypal SCRIPTING language has Classes and typing and build systems and cascading transpilers. I'm not saying we should go back to the bad ol' days of writing kitchen sink code for MVCs a billion times, but why do we need Typescript, Flow, Babel, Dart, Coffeescript, and Clojurescript? Why?
