Hi,

My code passes all the other tests except for ‘1 eye for of 1 eye’ - it should return false and it’s returning true.  
Any suggestions? I’m pretty happy with the logic I’ve come up with, but must be missing something…

function palindrome(str) {  
str = str.replace(/[^a-zA-Z0-9]/g,’’);  
str = str.toLowerCase();  
var test;  
for (i = 0; i \< (str.length/2); i++) {  
if (str[i] !== str[(str.length -1 - i)]) {  
test = false;  
}  
else {  
test = true;  
}

}  
return test;

}

palindrome(“1 eye for of 1 eye”);

I answered a similar problem before.

Thanks so much! I set my initial test variable to true and got rid of the else and it passed!

I still don’t get what you mean. I never had an else in my if-block and I am still getting that only input wrong.

My code below.

function palindrome(str) {  
// Good luck!  
str = str.replace(/[^a-z]/gi, ‘’);  
str = str.toLowerCase();  
var arraySplitStr = str.split(’’);  
var arrayReverseStr = arraySplitStr.reverse();  
var reverseStr = arrayReverseStr.join(’’);  
if(reverseStr !== str){  
return false;  
}  
return true;  
}

Like @rmdawson71 said, your code doesn’t take into account numbers in the string.
