Summary:
- XML (Extensible Markup Language) is a programming language used to create and structure data in a way that is easy for computers to read and understand.
- XML was once very popular for data exchange and web development, but its use has declined in recent years as newer technologies like JSON have become more widely adopted.
- However, XML still has important applications in areas like configuration files, data storage, and communication between different systems, making it a valuable tool for developers to understand.
