Create a Secret Society Name

A group of friends has decided to form a secret society, and they want to choose a unique and organized name for it. The name of the society will be formed using the first letter of each friend’s name, sorted alphabetically.

Instructions:

• Write a function named createSocietyName that takes one parameter:

  • names: An array of strings, where each string is a name of a friend.

• The function should return a string that represents the name of the secret society. The name is created by concatenating the first letter of each friend's name, sorted in alphabetical order.

Note: Only use the map, filter, or reduce methods, or a combination of these methods, to solve the problem. Do not use loops to iterate or perform the operation.
