How do I use structs in Go to work with JSON?

In Go, you can use structs to represent JSON objects. You define a struct with fields that match the JSON keys.

Can you show me an example of a struct for a JSON object?

Sure! For example, if you have a JSON object like { "name": "John", "age": 30 }, you can define a struct like this:

type Person struct {
    Name string `json:"name"`
    Age  int    `json:"age"`
}

How do I convert JSON to a struct and vice versa?

You can use the encoding/json package. To convert JSON to a struct, use json.Unmarshal(), and to convert a struct to JSON, use json.Marshal().

What if the JSON keys don't match the struct field names?

You can use struct tags to specify the JSON key names. For example, json:"name" tells Go to map the JSON key "name" to the struct field Name.
