Thank you for this article, I recently started learning JavaScript, and not only did I not understand how to properly use .map(), .filter() and .reduce(), but I also had a hard time figuring out why I should even use them (I’m learning from FreeCodeCamp as of right now, and they don’t do a great job at explaining why I should use something instead of something else at times).

Your article helped me understand those concepts and why I should use .map(), .filter() and .reduce() in my code.

Once again, thanks!
