Reverse method transpose all element so that the first array element becomes the last array
 element and last array element becomes the first array element.

//Example 1: reverse() Method for Array applied to string//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";

//Reverse all elements using reverse() method.var MyFavSong = objArray.reverse();

//Output of reverse method stored in MyFavSong String variable
Higher,and,Higher,Fire,On,Dreams



//Example 2: reverse() Method for Array applied to number//Declare of Array        var objArrayNum = new Array(6);

objArrayNum[0] = 1;
objArrayNum[1] = 2;
objArrayNum[2] = 3;
objArrayNum[3] = 4;
objArrayNum[4] = 5;
objArrayNum[5] = 6;

//Reverse all elements using reverse() method.var ReverseNum = objArrayNum.reverse();

//Output of reverse method stored in ReverseNum String variable
6,5,4,3,2,1



//Testing reverse method of arrayfunction 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";

            //Output of reverse Method
            alert(MyFavSong);

            //Reverse all elements using reverse() method.var MyFavSong = objArray.reverse();

            //Declare of Array        var objArrayNum = new Array(6);

            objArrayNum[0] = 1;
            objArrayNum[1] = 2;
            objArrayNum[2] = 3;
            objArrayNum[3] = 4;
            objArrayNum[4] = 5;
            objArrayNum[5] = 6;

            //Reverse all elements using reverse() method.var ReverseNum = objArrayNum.reverse();

            //In above statement reverse() Method reverse all elements//i.e. First element becomes last and last becomes first                        //Output of Reverse Number
            alert(ReverseNum);
    }
