JavaScript array object reference

In this Tutorial we want to describe you a code that helps you in
understanding JavaScript array object reference. For this we are using Java Scripting
language. We declare an array variable that is used to instantiate array class.
In order to set and access the value of the element in an array ,we must use index. The
document.write print the element in an array object. The for loop execute
the script till the variable i is less than length of an array. The
document.print list of element in an array object On clicking the button
the function function1 is invoked in which an array object call reverse method
returns you the reverse order of the element in the array. and store in a
variable c.The document.write print the Array after Reversing .For loop execute
the script till the var i is less than length of var c.Finally the dcument.print
print the element of an array in reverse order.
