The zero value of slice is nil. If a slice is declared like below, it is a nil slice. An empty slice is a slice also has a length and capacity of zero but has underlying array with length zero. If a slice is declared like below, it is an empty slice. In most cases, empty slice and nil slice can be treated the same. Only in some subtle cases, they should be treated differently, one of them is when doing JSON encoding.
