The Code is structured in three funtions

getValues

: This function acts as the entry point for the program. It retrieves the input string element with the ID 'userString.' The input is then passed to the checkForPalindrome() function. Finally, the results returned from checkForPalindrome() are displayed using the displayResults() function.

checkForPalindrome

This function performs the logic to check whether the input string is a palindrome. It starts by initializing an empty string 'revString' to store the reversed version of the input. It converts the input to lowercase and removes any non-alphanumeric characters using a regex expression. Then, it iterates through the characters of the input string in reverse order and builds the reversed string revString. After constructing the reversed string, the function creates an object palindromeObj with two properties: isPalindrome (a boolean indicating whether the input is a palindrome) and reversedString (the reversed version of the input). Finally, it returns palindromeObj with the results.

displayResults

This function is responsibl for displaying the results of the palindrome check. It first selects an HTML element with the ID 'alert' and removes the 'invisible' class to make it visible. Then, it updates the content of an HTML element with the ID 'msgReversed' to display the reversed version of the input string from the results object. Depending on whether the input is a palindrome (results.isPalindrome), it modifies the content and styling of an HTML element with the ID 'results' and the class of the 'alert' element. If it's a palindrome, a success message is displayed, and the 'alert-success' class is added to the 'alert' element; otherwise, an error message is displayed, and the 'alert-danger' class is added.
