Introduction:

Palindromes are fascinating word or number sequences that read the same forwards and backward. When it comes to programming, checking whether a given string is a palindrome or not is a common problem.

We'll

1. discuss the problem,
2. outline an approach,
3. present a step-by-step solution, and provide example code using JavaScript.

Understanding the Problem:

Given a string, we need to determine whether it is a palindrome or not. A palindrome is a string that remains the same when its characters are reversed.

My approach for solving this problem:

Step 1: Remove non-alphanumeric characters
The first step is to clean the input string by removing any non-alphanumeric characters. We can achieve this by using a regular expression and the replace() method. The regular expression /[^a-z0-9]/g matches any character that is not a letter or a digit. We replace these characters with an empty string to obtain a clean version of the input string.

Step 2: Reverse the cleaned string
Next, we split the cleaned string into an array of individual characters using the split() method. We then reverse the order of the characters in the array using the reverse() method. Finally, we join the reversed characters back into a string using the join() method.

Step 3: Compare the cleaned string with the reversed string
In the final step, we compare the cleaned string obtained in Step 1 with the reversed string obtained in Step 2. If both strings are equal, it means the original input string is a palindrome. Otherwise, it is not.

My solution:

function palindrome(str) {
  const regex = /[^a-z0-9]/g;
  const cleanStr = str.toLowerCase().replace(regex, "");
  const reverseStr = cleanStr.split("").reverse().join("");
  const isPalindrome = cleanStr === reverseStr;

  return isPalindrome;
}

palindrome("My age is 0, 0 si ega ym.");
