Convert javascript array to string

Converting From Array to String is So Easy !

var A = ['Sunday','Monday','Tuesday','Wednesday','Thursday']
array = A + ""

That's it Now A is a string. :)

If value is not a plain array, such code will work fine:

var value = { "aaa": "111", "bbb": "222", "ccc": "333" };
var blkstr = [];
$.each(value, function(idx2,val2) {                    
  var str = idx2 + ":" + val2;
  blkstr.push(str);
});
console.log(blkstr.join(", "));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

(output will appear in the dev console)

As Felix mentioned, each() is just iterating the array, nothing more.
