alert('The
Entered String "'+str +'" is "'+result+'"');
}
function
checkPalindrome(str)
{
var orignalStr;
//lowercase the

str =
str.toLowerCase();
//store the str
in orignalStr for future use
orignalStr =
str;
//reverse the
entered string
str =
str.split(''); //split the entered string
str =
str.reverse(); //reverse the order
str =
str.join(''); //then join the reverse order array values
var reverseStr
= str;
//finally check
both the Original string stored in orignalStr
//and reversed
to find the palindrom
if(orignalStr
== reverseStr){
return
'Palindrome'; // return "Palindrome" if true
}else{
return 'Not
Palindrome';
