looking @ following diagram (which explains mvc), see unidirectional data flow. so why consider mvc have bidirectional data flow while justifying flux ? because in javascript frameworks mvc not work way depicted. ui communicates bi-directionally model, in: user types view input mvc framework binds onchange() update model. ajax request brings in new model data. mvc framework updates view input's value match model. in flux architecture, ui fire independent action type , associated data dispatcher update model same way background ajax method update model. reference: http://www.thesoftwaresimpleton.com/blog/2013/03/23/client-side-mvc/ "client side mvc different server side mvc" "we setting 2 way communication between 2 objects..." "in short wiring value of firstname property of person object value property of input." http://guides.emberjs.com/v1.10.0/object-model/bindings/ bindings in ember.js can use

i have basic tvml application set up. simple events (such button press) handled via javascript (tvjs). when user presses button (provided via tvml template) i'd code run in swift instead, manipulates ui elements. what's best way this? you can use evaluateappjavascriptin method in tvapplicationcontrollerdelegate below , write corresponding swift method in it; (swift side) // mark: tvapplicationcontrollerdelegate func appcontroller(_ appcontroller: tvapplicationcontroller, evaluateappjavascriptin jscontext: jscontext){ let debug : @convention(block) (string!) -> void = { (string : string!) -> void in #if debug print("[log]: \(string!)\n") #endif } jscontext.setobject(unsafebitcast(debug, to: anyobject.self), forkeyedsubscript: "debug" (nscopying & nsobjectprotocol)!) } after can call method tvjs this; (js side) debug('hello js swift...');
