2.2

Exercise 2.2: Group therapy

This time, you'll need to define a generic slice type Group[E] to pass the following test:

func TestGroupContainsWhatIsAppendedToIt(t *testing.T) {
	t.Parallel()
	got := group.Group[string]{}
	got = append(got, "hello")
	got = append(got, "world")
	want := group.Group[string]{"hello", "world"}
	if !cmp.Equal(want, got) {
		t.Error(cmp.Diff(want, got))
	}
}

If you get stuck, have a look at Solution 2.2.
