Dreams on Fire Higher and Higher


//Testing Array Join Method function TestArray() {
    //Declare of Array        var objArray = new Array(6);

    objArray[0] = "Dreams";
    objArray[1] = "On";
    objArray[2] = "Fire";
    objArray[3] = "Higher";
    objArray[4] = "and";
    objArray[5] = "Higher";

    //Joins all elements using join method.var MyFavSong = objArray.join(" ");

            //In above statement Join Method joins all elements//With Space seperator//Output of Join Method
            alert(MyFavSong);
