Array is logical grouping of set of data.

Declaration of Array
//Declare One-Dimensional Array//Array Size is of 10var ArrayObj = new Array([ArrayLenght])

//Example of One-Dimensional Arrayvar objArray = new Array(10);


//Declaration of Multi-Dimensional Array//Array Size is of 10,10var ArrayObj = new Array([ArrayLenght],[ArrayLenght])

//Example of Multi-Dimensional Arrayvar objArray = new Array(10,5);


Following Example will show how to use one dimensional array declaration
function OneDimensionArray() {
            //Declare One-Dimensional Array//Array Size is of 10var objArray = new Array(10);

            //Looping through Array and Assign Valuefor (i = 0; i < 10; i++) {
                objArray[i] = i;
            }

            //Displaying value of Arrayfor (i = 0; i < 10; i++) {
                alert("Value of objArray[" + i + "]: " + objArray[i]);
            }
        }


Following Example will display how to use Two-Dimensional Array
function TwoDimensionArray() {
            //Declare Two-Dimensional Array//Array Size is of 10var objArray = new Array(5,10);

            //Looping through Array and Assign Valuefor (i = 0; i < 10; i++) {
                objArray[i] = i;
            }

            //Displaying value of Arrayfor (i = 0; i < 5; i++) {
                for (j = 0; j < 10; j++) {
                    alert("Value of objArray[" + i + ", " + j +"]: " + objArray[i,j]);
                }
            }
        }

Following Example will display output of Two-Dimensional Array
