+#### Palindrome Checker
+
+Return `true` if the given string is a palindrome. Otherwise, return `false`.
+
+A palindrome is a word or sentence that's spelled the same way both forward and backward, ignoring punctuation, case, and spacing.
+
+Note
+You'll need to remove all non-alphanumeric characters (punctuation, spaces and symbols) and turn everything into the same case (lower or upper case) in order to check for palindromes.
+
+We'll pass strings with varying formats, such as `"racecar"`, `"RaceCar"`, and `"race CAR"` among others.
+
+We'll also pass strings with special symbols, such as `"2A3*3a2"`, `"2A3 3a2"`, and `"2_A3*3#A2"`.
+
+```javascript
+export function palindrome(str) {
+  const normalizedStr = str.toLowerCase().split(/[\W_]+/).join('');
+  return normalizedStr === normalizedStr.split('').reverse().join('');
+}
