However, JSON documents can have more complex structures with multiple depth levels.

Before seeing some code, I think that it would be very useful to talk about the encoding/json Go package first. The encoding/json package offers the Encode() and Decode() functions that allow the conversion of a Go object into a JSON document and vice versa. Additionally, the encoding/json package offers the Marshal() and Unmarshal() functions that work similarly to Encode() and Decode() and are based on the Encode() and Decode() methods.

The main difference between Marshal()-Unmarshal() and Encode()-Decode() is that the former functions...
