Convert Struct to JSON in Golang

package main

import (
	"encoding/json"
	"fmt"
)

type Product struct {
	Id       string  `json:"id"`
	Name     string  `json:"name"`
	Price    float32 `json:"price"`
	Quantity int     `json:"quantity"`
	Status   bool    `json:"status"`
}

func main() {
	product := Product{"p01", "name 1", 2, 5, true}
	str, _ := json.Marshal(product)
	fmt.Println(string(str))
}

Output

{"id":"p01","name":"name 1","price":2,"quantity":5,"status":true}
