How do I encode Go structs to JSON?

How do I encode Go structs to JSON?

You can use the encoding/json package in Go. The json.Marshal function converts a struct to JSON.

Can you show me a simple example?

Sure! Here's a basic example:

package main

import (
    "encoding/json"
    "fmt"
)

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

func main() {
    p := Person{Name: "Alice", Age: 30}
    jsonData, err := json.Marshal(p)
    if err != nil {
        fmt.Println(err)
    }
    fmt.Println(string(jsonData))
}

What if my struct has nested structs?

The json.Marshal function handles nested structs automatically. Just define your structs normally, and it will encode them.
