Why does javascript change objects into other things when added? -

something interesting adding empty arrays in javascript pointed out me, , have no idea why works way does. adding empty arrays results in string. in other terms, [] + [] returns "" i booted console test it, , sure enough, works. further discovered behavior not limited empty arrays. arrays of numbers, strings, arrays, , objects turn strings when added other array. examples are: [1] + [] //returns "1" [1] + [2] //returns "12" [1,2,3] + [2] //returns "1,2,32" [{foo:'bar'},'foo','bar'] + [] //returns "[object object],foo,bar" it occurs other objects, when added else, if object on right hand side. if it's on left hand side, object turned 0. 'foo' + {foo:'bar'} //returns "foo[object object]" 1 + {foo:'bar'} //returns "1[object object]" {foo:'bar'} + 1 //returns 1 {foo:'bar'} + 'foo' //returns nan this happens unless assign object

objective c - Does -[NSInvocation retainArguments] copy blocks? -

nsinvocation 's -retainarguments method useful when don't run nsinvocation immediately, later; retains object arguments remain valid during time. as know, block arguments should copied instead of retained. question is, -retainarguments know copy instead of retain argument when it's of block type? documentation not indicate does, seems easy , sensible thing do. update: behavior seems have changed in ios 7. tested this, , in ios 6.1 , before, -retainarguments didn't copy parameters of block type. in ios 7 , later, -retainarguments copy parameters of block type. documentation of -retainarguments has been updated copies blocks, not when behavior changed (which dangerous people support older os's). it's supposed (albeit haven't test myself). according documentation : retainarguments if receiver hasn’t done so, retains target , object arguments of receiver , copies of c-string arguments , blocks.
