Description

Hello, When I do something like that on an Android (note that this code shouldn't exists at all in "builded code") :

if(OS_IOS){
	const test = 'my string';
}

I have this error:

[ERROR] :  TiExceptionHandler: (main) [128,128] ----- Titanium Javascript Runtime Error -----
[ERROR] :  TiExceptionHandler: (main) [1,129] - In /app.js:60,10
[ERROR] :  TiExceptionHandler: (main) [0,129] - Message: Uncaught SyntaxError: Missing initializer in const declaration
[ERROR] :  TiExceptionHandler: (main) [0,129] - Source: const test;
[ERROR] :  V8Exception: Exception occurred at /app.js:60: Uncaught SyntaxError: Missing initializer in const declaration

And when I go the the "builded" file I have something like that :

const test;

Which is not good because "const" need to been initialized ... And also not good because const is block scoped !

Hello, I can't reproduce the issue with the below code. In Android I don't run into any error.

   var win = Ti.UI.createWindow({
   
       backgroundColor : 'white'
   
   });
   var osname = Ti.Platform.osname;
   
   var OS_IOS = (osname == 'iOS') ? true : false;
   
   if (OS_IOS) {
   
       const test = 'my string';
   
   }
   
   win.open();

Can you provide a full sample code to reproduce. I am testing on SDK 6.0.1.GA. Thanks.
