Create a Palindrome using JavaScript and Recursion: A Step-by-Step Guide

Have you ever wanted to transform a number into a palindrome? A palindrome is a number that reads the same backward as forward, like 121 or 4884. In this guide, we'll break down how to create a function that takes a number and returns a palindrome by summing it with its reverse number. Even better, we’ll tackle this problem using recursion, a powerful tool in programming. Let’s dive into the details!

Understanding the Problem

To convert a number into a palindrome, we can follow this simple approach:

Take the original number.

Reverse its digits to get a new number.

Sum the original number with this reversed number.

Check if the result is a palindrome.

If it is not, repeat the process with the new sum until we get a palindrome.

Example Scenario

Start with the number 312.

Reverse it to get 213.

Add them together: 312 + 213 = 525, which is a palindrome!

However, some numbers, like 96, require more iterations to reach a palindrome.

Implementation in JavaScript

Now that we understand the logic, let's see how to implement it in JavaScript using recursion. Below is a sample code that demonstrates this approach:

Code Breakdown

Convert Number to String: The function num.toString() converts the number to a string format to allow for easy manipulation of its characters.

Reverse Logic: Using split(""), we divide the string into an array of characters. The reverse() method then reverses this array, and join("") combines it back into a string.

Palindrome Check: We compare the original string with the reversed version. If they are identical, we have our palindrome.

Recursion: If not, we calculate the new number by adding the original number to the reversed number, and call the function findPalindrome() again with this new sum.

Conclusion

Creating palindromes in JavaScript using recursion is not just a fun coding challenge; it’s also a great way to practice your recursive thinking and improve your understanding of functions. With the example provided, you can now create your own palindrome creator using these principles. Give it a try, and see how many iterations it takes with different numbers! Happy coding!
