What is JSON?

JSON (JavaScript Object Notation) is a way to store and share data in a simple text format. It’s commonly used in websites and apps for sharing data. Many online services (like weather apps or social media) send data in JSON format because:

• It is easy for people to read and for computers to understand.

• Websites and apps use JSON to save settings, send data, and load content.

• Its interoperability—data sharing between different programming languages and systems.
