`stringUtils` is a simple utility module that provides functions for common string operations.

// Function to reverse a string
function reverse(str) {
    return str.split('').reverse().join('');
  }
  
  // Function to convert a string to uppercase
  function toUpperCase(str) {
    return str.toUpperCase();
  }
  
  // Function to convert a string to lowercase
  function toLowerCase(str) {
    return str.toLowerCase();
  }
  
  // Function to check if a string is a palindrome
  function isPalindrome(str) {
    const cleanedStr = str.replace(/[^a-zA-Z0-9]/g, '').toLowerCase();
    return cleanedStr === reverse(cleanedStr);
  }
  
  // Export the functions to make them available for use in other files
  module.exports = {
    reverse,
    toUpperCase,
    toLowerCase,
    isPalindrome,
  };
