(See also [Windows Runtime Direct API Access Event Handling|http://docs.appcelerator.com/platform/latest/#!/guide/Windows_Runtime_Direct_API_Access-section-src-43315893_WindowsRuntimeDirectAPIAccess-EventHandling]).  \r\n\r\nBut yes, this should be an interesting point to discuss. Basically on Windows, C\\+\\+/CX uses {{+=}} to represent \"add event listener\" function like below. But the question is, do we have better style to represent this in JavaScript syntax?\r\n\r\n{code:title=C++/CX}\r\nclick_event_ = component->Tapped += ref new TappedEventHandler([this, ctx](Platform::Object^ sender, TappedRoutedEventArgs^ e) {\r\n    // do something\r\n});\r\n{code}\r\n\r\nCurrently we've been using {{addEventListener}} for this like below.\r\n\r\n{code:title=JavaScript}\r\ncomponent.addEventListener('Tapped', function(e) {\r\n    // do something\r\n});\r\n{code}\r\n\r\nI was thinking {{addEventListener}} can be more familiar for JavaScript developers.\r\n\r\nWe could do like below, regarding following C\\+\\+ syntax...but is this better?\r\n\r\n{code:title=JavaScript}\r\ncomponent.Tapped += function(e) {\r\n    // do something\r\n};\r\n\r\nOr...?\r\n\r\ncomponent.Tapped += new TappedEventHandler(function(e) {\r\n    // do something\r\n});\r\n{code}\r\n\r\nWe could have better way to do this, any suggestions would be appreciated!
