How Does Browser-Native JSON Support Enhance Object Parsing and Serialization?

Browser-Native JSON Support with window.JSON: Explained

Native JSON support has been integrated into modern browsers, providing an efficient way to parse and serialize objects using the window.JSON object.

Supported Browsers:

• Internet Explorer 8
• Firefox 3.1
• Safari 4
• Chrome 3

Exposed Methods:

window.JSON exposes the following methods:

• parse(str): Parses a JSON string (str) and returns an object.
• stringify(obj): Converts an object (obj) into its JSON representation.

Example Usage:

<code class="javascript">const jsonStr = '{"name": "John", "age": 30}';
const obj = JSON.parse(jsonStr); // Parse JSON string into object

const data = { name: "Mary", age: 40 };
const json = JSON.stringify(data); // Convert object to JSON string</code>

Advantages:

• Native JSON support optimizes parsing and serialization for both speed and security.
• It eliminates the need for external libraries or custom implementations.
• JSON strings can be seamlessly transmitted and exchanged between web pages and servers.
