Convert javascript array to string

Question

I\'m trying to iterate over a \"value\" list and convert it into a string. Here is the code:

var blkstr = $.each(value, function(idx2,val2) {                        


        

Answer 1

var arr = new Array();

var blkstr = $.each([1, 2, 3], function(idx2,val2) {                    
    arr.push(idx2 + ":" + val2);
    return arr;
}).join(', ');

console.log(blkstr);

OR

var arr = new Array();

$.each([1, 2, 3], function(idx2,val2) {                    
    arr.push(idx2 + ":" + val2);

});

console.log(arr.join(', '));
