In JavaScript, working with JSON is straightforward because JSON is a native part of the language. JavaScript provides JSON.parse() to convert a JSON string into a JavaScript object and JSON.stringify() to convert a JavaScript object into a JSON string.
// JSON to JavaScript object
var jsonString = '{"name": "John", "age": 30}';
var jsonObject = JSON.parse(jsonString);
// JavaScript object to JSON
var person = { name: "Alice", age: 25 };
var jsonString = JSON.stringify(person);
In Python, the json module is used to work with JSON data. It provides the json.loads() function to parse a JSON string into a Python object and json.dumps() to convert a Python object into a JSON string.
import json
# JSON to Python object
json_string = '{"name": "Bob", "age": 35}'
python_object = json.loads(json_string)
# Python object to JSON
person = {"name": "Eve", "age": 28}
json_string = json.dumps(person)
In Java, the Jackson library or Gson library is commonly used for JSON processing. You can use these libraries to serialize Java objects into JSON and deserialize JSON into Java objects.
import com.fasterxml.jackson.databind.ObjectMapper;
// JSON to Java object
String jsonString = "{\"name\":\"Charlie\",\"age\":40}";
ObjectMapper objectMapper = new ObjectMapper();
Person person = objectMapper.readValue(jsonString, Person.class);
// Java object to JSON
Person person = new Person("David", 45);
String jsonString = objectMapper.writeValueAsString(person);
In C#, the System.Text.Json namespace provides classes for working with JSON. You can use JsonSerializer.Deserialize() to parse JSON into C# objects and JsonSerializer.Serialize() to convert C# objects into JSON.
// JSON to C# object
string jsonString = "{\"name\":\"Harry\",\"age\":50}";
Person person = JsonSerializer.Deserialize(jsonString);
// C# object to JSON
Person person = new Person { Name = "Grace", Age = 55 };
string jsonString = JsonSerializer.Serialize(person);
In Ruby, the json module is part of the standard library, making it easy to work with JSON. You can use JSON.parse() to parse a JSON string into a Ruby object and JSON.generate() to convert a Ruby object into a JSON string.
require 'json'
# JSON to Ruby object
json_string = '{"name": "Helen", "age": 60}'
ruby_object = JSON.parse(json_string)
# Ruby object to JSON
person = { "name" => "Ivy", "age" => 65 }
json_string = JSON.generate(person)
These examples illustrate how JSON is commonly used in various programming languages for data interchange. The specific libraries or modules used may vary, but the general process remains consistent across languages.
