What are the historical differences between JSON and XML?

JSON (JavaScript Object Notation) was introduced in the early 2000s, while XML (eXtensible Markup Language) dates back to the late 1990s. XML was designed for data interchange and document representation, whereas JSON was created to be a lightweight data interchange format, primarily for use with JavaScript.

Why did JSON become more popular than XML?

JSON's popularity surged due to its simplicity and ease of use, especially in web applications. It has a more concise syntax compared to XML, making it easier to read and write. Additionally, JSON's compatibility with JavaScript made it a natural choice for web developers.

Are there any scenarios where XML is still preferred?

Yes, XML is still preferred in scenarios requiring complex data structures, such as document formats (like SVG or XHTML) and when extensive metadata is needed. It also supports namespaces, which can be beneficial in certain applications.

What are some key features of JSON?

Key features of JSON include its lightweight nature, easy readability, support for various data types (like strings, numbers, arrays, and objects), and its seamless integration with JavaScript, making it ideal for web APIs.
