Hey fellow developers! 👋 Welcome to today's JavaScript coding challenge. Let's keep those programming skills sharp!
The Challenge

Description
Given a sequence of consecutive letters in the alphabet, find the missing letter in the sequence. The function receives an array of lowercase characters representing a range from any starting letter of the alphabet to ending.

tried an approach without using the charCodeAt
but miss the challenge, looks like we can't post answer to old challenge 🤔
Thanks for your comment! Very very soon you will be able to code on old challenges! Currently working on it
Thank you for all the effort! It’s already great as it is—even without access to old challenges👏✨
