JSON
JSON (JavaScript Object Notation) is a lightweight data format used for transmitting data between servers and web/mobile applications.
Why It Matters
JSON is the universal language of web and mobile APIs—understanding it is essential for anyone working with modern applications.
When to Use This
- API request and response payloads
- Configuration files
- Data storage and caching
- Real-time data streaming
Examples
- API returning {"name": "John", "email": "john@example.com"}
- Vue component receiving product data as JSON props
- Redis storing JSON-serialized session data
