chatroomStatus.js

// Write a function that returns the number of users in a chatroom based on the following rules:
// If there is no one, return "no one online".
// If there is 1 person, return "user1 online".
// If there are 2 people, return "user1 and user2 online".
// If there are n>2 people, return the first two names and add "and n-2 more online".
// For example, if there are 5 users, return:
// "user1, user2 and 3 more online"

// Examples:
// chatroomStatus([]) ➞ "no one online"
// chatroomStatus(["paRIE_to"]) ➞ "paRIE_to online"
// chatroomStatus(["s234f", "mailbox2"]) ➞ "s234f and mailbox2 online"
// chatroomStatus(["pap_ier44", "townieBOY", "panda321", "motor_bike5", "sandwichmaker833", "violinist91"])
// ➞ "pap_ier44, townieBOY and 4 more online"
