How can I use advanced JSON structs in Go?

In Go, you can define complex JSON structures using nested structs and maps. Would you like an example?

Yes, please provide an example of a nested struct.

Sure! Here's a simple example:

type Address struct {
    Street string `json:"street"`
    City   string `json:"city"`
}

type User struct {
    Name    string  `json:"name"`
    Age     int     `json:"age"`
    Address Address `json:"address"`
}

This defines a User struct that contains an Address struct.

How do I marshal and unmarshal this struct?

You can use the json.Marshal and json.Unmarshal functions. For example:

user := User{Name: "John", Age: 30, Address: Address{Street: "123 Main St", City: "Anytown"}}
jsonData, _ := json.Marshal(user)

var newUser User
json.Unmarshal(jsonData, &newUser)
