Say Hello to Guests

In this exercise you will have to:

• Take a list of names.
• Add "Hello" to every name.
• Make one big string with all greetings.

The solution should be one string with a comma in between every "Hello (Name)".

Examples

greetPeople(["Joe"]) ➞ "Hello Joe"

greetPeople(["Angela", "Joe"]) ➞ "Hello Angela, Hello Joe"

greetPeople(["Frank", "Angela", "Joe"]) ➞ "Hello Frank, Hello Angela, Hello Joe"

Notes

• Each greeting has to be separated with a comma and a space.
• If you're given an empty array [], return an empty string "".
