My solution in Javascript

const missing = arr => {
  const alphabet = "abcdefghijklmnopqrstuvwxyz".split("");
  arr = arr.map(item => item.toLowerCase());
  for (let i in arr) {
    if (!arr.includes(alphabet[alphabet.indexOf(arr[i]) + 1]))
      return alphabet[alphabet.indexOf(arr[i]) + 1]
  }
}
