}About JSON Files
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is widely used for transmitting data between a server and web application.
Common Use Cases
- API responses and requests
- Configuration files
- Data storage and exchange
- Web application state management
JSON Structure
JSON supports several data types including strings, numbers, booleans, null, arrays, and objects. Objects are collections of key-value pairs enclosed in curly braces, while arrays are ordered lists enclosed in square brackets.
