Hello NQE Enthusiasts,

I’ll try to post a new Koan Challenge every two months.

Challenge

This task is to take the following table and group people by age.

Input

 [{ Name: "Bob", Age: 21 },

  { Name: "Sam", Age: 19 },

  { Name: "Jill", Age: 18 },

  { Name: "Jim", Age: 21 },

  { Name: "Sally", Age: 19 }

 ];

Example Result

[{Age: 21, Count: 2}...]
