Like the title says, i would like to remove an underscore within a String with a regex. This is what i have:

  function palindrome(str) {



     str = str.toLowerCase().replace(/[^a-zA-Z]/g, '',/s/g, '',/[0-9]/g,'');  

        if (str.split().reverse().join() !== str) {

           return false;

        }

        else {

           return true;

        }

   }

palindrome(eye);

Use .replace(/_/g, ) to remove all underscores or use .replace(/_/g, ) to replace them with a space.

Here is an example to remove them:

var str = Yeah_so_many_underscores here;

var newStr = str.replace(/_/g, );

alert(newStr);
