Contoh JSON dalam 7 Bahasa: JavaScript, Python, Go, Rust, PHP, Java, C#

// Parse a JSON string into an object
const data = JSON.parse('{"name": "Alice", "age": 30}');
console.log(data.name); // "Alice"

// Serialize an object back to JSON
const json = JSON.stringify(data, null, 2);

// Fetch JSON from an API
const res = await fetch("/api/users/1");
const user = await res.json(); // parsed automatically

import json

# Parse JSON string into a dict
data = json.loads('{"name": "Alice", "age": 30}')

# Serialize a dict to a pretty JSON string
text = json.dumps(data, indent=2, ensure_ascii=False)

# Read/write a JSON file
with open("data.json", encoding="utf-8") as f:
    data = json.load(f)

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

// Struct → JSON
b, _ := json.Marshal(User{Name: "Alice", Age: 30})

// JSON → struct
var u User
_ = json.Unmarshal([]byte(`{"name":"Bob","age":25}`), &u)

<?php
// PHP array → JSON
$json = json_encode(["name" => "Alice", "age" => 30],
    JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE);

// JSON → PHP array
$data = json_decode($json, true);
if (json_last_error() !== JSON_ERROR_NONE) {
    echo "JSON error: " . json_last_error_msg();
