I loved the way you could start with a static HTML mockup with Angular, then add the boilerplate in a single .js file, then define a simple data model in the js, slap in some curly braces and ng-model attributes hit "reload" and try it out, lather, rinse, repeat -- all without any build (transpile, concat) step. Angular 2 looks like a JEE "inspired" nightmare.
