Marshalling

Unmarshaling

To read data from JSON received from over the internet, we need to Unmarshall it first

json.Unmarshal(reqBody, &article)

Before we unmarshall the JSON, it is represented as an array of bytes.

Marshal

json.NewEncoder and json.Marshal both marshal objects into JSON encoded strings.

• The difference being that the Encoder first marshals the object to a JSON encoded string, then writes that data to a buffer stream. The Encoder therefore, uses more code and memory overhead than the simpler json.Marshal.

• Encoding/decoding JSON refers to the process of actually reading/writing the character data to a string or binary form.

• Marshaling/Unmarshaling refers to the process of mapping JSON types from and to Go data types and primitives.

• In Go, struct data is converted into JSON using Marshal() and JSON data to string using Unmarshal() method.
