But I guess I'd better ask a more constructive question.
Is this similar to "Reactjs" from Facebook?
On a higher level, is this a more 'trending' approach to build large JS apps? (e.g. there is also a google Polymer project right?).
Seems like we are moving away from the BackboneJS, EmberJS, AngularJS type of approach to a 'compartmentalized' or a component-based approach?
You can use whatever JS framework you want. It does however come bundeled with Knockout and Presenter (which is based on knockout).
Disclamer: I work for Caplin which is the author of BladeRunnerJS
Which part of the "stack" does it replace - the build toolchain? Organisation methodologies? Or "frameworky" stuff like the design pattern?
It's just I vastly prefer the current ReactJS way of doing stuff to simple data-binding, so I'm rather sceptical of switching away from it.
BRJS is "just" about organising things, build toolchain (to an extent) and it also provides some libraries like emitter, service/alias registry, etc. But you don't have to use any of that. We are working on putting JsDocs on the website (they are there if you download it), that will hopefully make it more clear on what's included.
If you are interested we do have som edocuments on the page explaining all the concepts in BRJS.
Is this "emacs" thing similar to django?
