jsonArray concatenate not working : Hi Friends I am trying to merge two json arrays i have tried concat and merge method but it's not giving the correct output please suggest something...

    var set_image=[{"id":"aerobics"},{"id":"kick boxing"}]
    var item_json=[{"id":"net ball"},{"id":"floor ball"}]

Merged Array

    var finalArray =[{"id":"aerobics"},{"id":"kick boxing"},{"id":"net ball"},{"id":"floor ball"}]


Here is my javascript

    var item = JSON.parse(localStorage.getItem("test"));
	var item_json = JSON.stringify(item) ;
	
	var page= <?php echo $json_value; ?>;
	var set_image=JSON.stringify(page) ;
	
	
	//var image=set_image.concat(item_json);
	var image= $.concat(set_image, item_json)
	
	
    window.location.href = "modal.php?ids=" + image;
