Can you give me examples of JSON structs in Go?

Sure! In Go, you can define a struct to represent JSON data. For example:

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

This struct can be used to marshal and unmarshal JSON.

How do I unmarshal JSON into this struct?

You can use the json.Unmarshal function. Here's an example:

jsonData := `{"name":"John", "age":30}`
var person Person
err := json.Unmarshal([]byte(jsonData), &person)
if err != nil {
    log.Fatal(err)
}
fmt.Println(person)

This will populate the person variable with the data from the JSON.

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

You can use struct tags to specify the JSON keys. For example:

type Person struct {
    Name string `json:"full_name"`
    Age  int    `json:"years"`
}

In this case, the JSON keys full_name and years will map to the struct fields.
