I'm trying to pass this test I was given, but I haven't gotten pretty far.

describe('closures pt.2', () => {
    it(`take an array and return an object with three functions:
        * pluck: Takes a key name and returns an array of the value matching that key for each item in the array.
        * inc: Takes an integer and updates the "count" value for each item in the array by adding the argument to the current count.
        * get: Takes a string and returns the item in the array whose name matches the string.
      `, () => {
      const arr = [
        {
          name: 'foo',
          count: 1
        },
        {
          name: 'bar',
          count: 3
        },
        {
          name: 'baz',
          count: 0
        }
      ];

      const wrappedArray = wrapArr(arr);

      expect(wrappedArray.pluck('name')).toEqual(['foo', 'bar', 'baz']);
      expect(wrappedArray.pluck('count')).toEqual([1, 3, 0]);
      wrappedArray.inc(3);
      expect(wrappedArray.pluck('count')).toEqual([4, 6, 3]);
      expect(wrappedArray.get('bar')).toEqual({ name: 'bar', count: 4 });
    });
  });
