Both JSON and XML are used for storing and transferring structured data, but they're built differently and serve slightly different purposes.
JSON (JavaScript Object Notation) is a lightweight, easy-to-read data format based on JavaScript syntax.
{ "name": "Alex", "age": 25, "skills": ["C#", "Python", "JSON"] }
XML (eXtensible Markup Language) uses custom tags to store data and describe its structure. Itβs more verbose than JSON.
<person> <name>Alex</name> <age>25</age> <skills> <skill>C#</skill> <skill>Python</skill> <skill>JSON</skill> </skills> </person>
