dojo - Javascript (0 && 1) -

i'm trying debug javascript code related dojo localization, , came across following code in dojo:

isxd = function(mid, contextrequire){     return ( 0  &&  1 ) ?         contextrequire.isxdurl(require.tourl(mid + ".js")) :     true; }, 

what purpose of ternary operator here? seems me (0 && 1) false , function return true. browser compatibility thing?

^{the source i've found differs bit code, explanation should fit.}

the original code can found in i18n.js part of full source package:

isxd = function(mid, contextrequire){     return (has("dojo-sync-loader") && has("dojo-v1x-i18n-api")) ?         contextrequire.isxdurl(require.tourl(mid + ".js")) :         true; }, 

the same part in i18n.js.uncompressed.js included in release package looks this:

isxd = function(mid, contextrequire){     return ( 1  &&  1 ) ?         contextrequire.isxdurl(require.tourl(mid + ".js")) :         true; }, 

when take @ the dojo loader section "options/features", you'll see dojo-sync-loader has default value true.

the documentation states:

the first column option/feature defined within loader, second options whether detected feature (via has.add()) or if option , default value. “unbuilt” source, features , options available. if loader has been built, of these features may have been set statichasfeatures , not configurable anymore.

as dojo-sync-loader non-detectable feature, replaced in built source.
