Javascript Create, Add, Delete, Split, Join Array

Javascript Array Can be created As,

  var arry = [];
  var arry2=[''a","b","c"];

Array element can be added by:

arry.push("new element of arry");
arry.push("second element of arry");

Array element can be deleted by:
    var element_to_be_deleted= "new element of arry";
                        while (arry.indexOf(element_to_be_deleted) !== -1) {
                            items.splice(items.indexOf(element_to_be_deleted), 1);
                        }

It Completely removes element matching that name or index.

Array Can be join by
arry.join("seperator"); where seperator may me comma, any symbol.

If i join all elements of array by comma(,)

I can do,
var joinedSingleobj =  arry.join(" , ");

I can split string type variable to array by:

var str = " 'first_str' , 'seecond_str'";
var array=str.split(",");
