Check for Palindromes - .reverse() on array not working

JavaScript
1

Using the Chrome Dev Tools to view the console, my array, ‘reverseStr’ doesn’t seem to be '.reverse()'ing properly, or the order of the array does not change and I can’t figure out why. I’ve tried different means of initializing they array to start, in case some how the datatype was wrong, but with no luck.

Further, if the string portion of the console output is omitted, one can definitely see they are data of ‘array’ type. Any thoughts as to why this is not working ?

Your code so far

function palindrome(str) {
  // Good luck!
  lowerCaseStr = str.toLowerCase();
  lowerCaseStr = lowerCaseStr.replace(/\W/gi,'').replace(/_/g,'');
  var originalStr = lowerCaseStr.split('');
  var reverseStr = originalStr.reverse();

 console.log("Org Str" + originalStr);
 console.log("Rev Str" + reverseStr);
 
}
palindrome("eye");

The reverse() method actually reverses the array in place, so both originalStr and reverseStr are reversed.
Array.prototype.reverse()

Thanks Ariel,

I see this better now. Using .slice(0), rather than the assignment operator to copy data, not just the pointer.

Thanks.
