// Quas : WHAT IS ARRAY AND HOW TO DECLARE ARRAY ?
// array is a single variable that is used to store different many of elements.
declare Array :
First you have to write var.
then you have to write a meaningful name.
then you have to give an equal sign.
then you have to give a third bracket.
then you have to give a single quotation inter the third bracket.
then you have to give a element inter the single quotation.
then you have to give a comma.
then you have to give a semicolon out of the third bracket .
example :
var friendsName = ['habib', 'iqbal', 'shorif', 'asraful', 'rasel', 'arif', 'deader' ];
