JSON Serialization and Deserialization in Go

Learn how to serialize Go structs into JSON and deserialize JSON data into Go structs for data exchange and storage.

package main

import (
    "encoding/json"
    "fmt"
)

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

func main() {
    // Serialization (struct to JSON)
    person := Person{"Alice", 30, "alice@example.com"}
    jsonData, _ := json.Marshal(person)
    fmt.Println("JSON:", string(jsonData))

    // Deserialization (JSON to struct)
    jsonStr := `{"name":"Bob","age":25,"email":"bob@example.com"}`
    var newPerson Person
    json.Unmarshal([]byte(jsonStr), &newPerson)
    fmt.Println("Name:", newPerson.Name)
}
