Write a program to assign a list of employees into small lunch groups can be done in Javascript.

Requirements

New Employees

When someone joins the company, we want to add them to the list of people going to lunch.

Persistence

With over 100 employees, adding everyone from scratch is not sustainable. Once someone has been added, they should remain in the list across restarts.

Lunchtime

On Fridays, we want to assign everyone randomly into lunch groups. Each group should be between 3-5 people.

Example

Say we were in the business of mining precious gems and had these 8 employees:

[Happy, Dopey, Grumpy, Sneezy, Bashful, Sleepy, Doc, Snow]

When we shuffle everyone into lunch groups, one valid output would be:

Group 1 Group 2
Bashful Doc
Happy Grumpy
Sneezy Snow
Sleepy Dopey

Another valid output would be:

Group 1 Group 2
Bashful Doc
Happy Grumpy
Sneezy Snow
Sleepy
Dopy
