[Hacktoberfest 2025] Add jest test implementation to a kata folder

[dyarawilliams]

Description

As part of Hacktoberfest 2024, we are looking for contributors to implement Jest tests for individual kata solutions in the repository. This issue involves selecting a specific kata folder that currently lacks automated testing and adding a Jest test file to validate the solution.

Tasks

• Select one kata folder that does not already have a test file.
• Create a corresponding test file (e.g., kataName.test.js) in the directory of the kata of your choice.
• Write unit tests using Jest to validate the functionality of the kata solution.
• Ensure that all edge cases are considered and tested.
• Verify that the tests run successfully using npm test.

Expected Outcome

• The selected kata will have a fully functional Jest test implementation.
• Tests should cover various input scenarios and provide clear feedback if the solution is incorrect.

How to Contribute

• Comment below to claim this issue. Only one contributor per kata folder.
• Read the CONTRIBUTING.md file

Additional Information

This issue is part of our Hacktoberfest initiative to encourage open-source contributions. It’s a great opportunity to practice test-driven development (TDD) and improve the quality of kata solutions in the repository.
