Wow apple is embracing javascript

  How is this news?

    Because they don't do that for iOS, MacOS or watchOS? The last time they did something similar was for Dashboard Widgets and that was 10 years ago.

      AFAIK, the "Channels" on the Apple TV gen 2 and 3 are already JavaScript and XML-based (a while ago, people discovered that they could spoof the XML and JS on the Trailers channel to play arbitrary videos). So it's somewhat natural that the new Apple TV continues with Javascript.

      Apple introduced Native JavaScript bridge for iOS in iOS 7. you can call objective-c apis in javascript.[1] [1]https://developer.apple.com/library/mac/documentation/AppleApplications/Conceptual/SafariJSProgTopics/Tasks/ObjCFromJavaScript.html https://developer.apple.com/library/mac/documentation/AppleA...

        That's not what this is about though, it's for UI layout (much like with Dashboard). You don't call Objective-C APIs from JS inside a WebKit container, you're actually using JS to layout the app. Update: the docs are up and the JS framework is called TVJS, https://developer.apple.com/library/prerelease/tvos/documentation/TVMLJS/Reference/TVJSFrameworkReference/index.html https://developer.apple.com/library/prerelease/tvos/document...

          JavaScriptCore framework gives full access to JS runtime.https://www.bignerdranch.com/blog/javascriptcore-and-ios-7/ https://www.bignerdranch.com/blog/javascriptcore-and-ios-7/

          The docs say you use something called "TVML" to lay out the UI, and inside the TVML you can have JS. I think.
          • jonknee 11y ago
            TVML for layout and TVJS for logic. TVML is just an XML schema for Apple TV UIs and TVJS a Javascript framework to present the XML templates loaded with your data. If you're wanting to stream video you can build a full app with almost no Obj-C/Swift (there's still a small shell, though probably nothing custom needs to be here). The XML templates are a little odd in that they're JS files (e.g. Index.xml.js) and contain the XML as the return value of a global function called Template. It seems really straight forward though.

                It's a fine use of XML. JSON would be a kludge. The templates look like this: <lockup> <img src="${this.BASEURL}resources/images/music/music_570_e1.lcr" width="450" height="450" /> <title class="showTextOnHighlight">Title 1</title> </lockup>

                  I wonder if they're being processed as ES6 Template Strings?

      You can write native apps in Javascript on the Mac. You can use Javascript from the command line out of the box in OSX.
