Challenge:: palindrome words : <p>A palindrome is a word that reads the same backward or forward.
Write a function that checks if a given word is a palindrome. Character case should be ignored.
function isPalindrome(word)
For example, isPalindrome("Deleveled") should return true as character case should be ignored, resulting in "deleveled", which is a palindrome since it reads the same backward and forward.</p>

<pre><code>function isPalindrome(word)
{
  // Please write your code here.
}
var word = readline()
print(isPalindrome(word))
</code></pre>
