Where json is used?

JSON is used extensively across modern software development. Web APIs predominantly use JSON for request and response payloads, enabling communication between clients and servers. Configuration files in tools like VS Code, npm, and webpack use JSON format for settings. NoSQL databases like MongoDB store data in JSON-like document structures. Mobile applications use JSON for data exchange with backend services. Single-page applications fetch and send JSON data asynchronously for dynamic content updates. Microservices architectures rely on JSON for inter-service communication. Logging systems output structured logs in JSON format for easier parsing and analysis. Cloud services use JSON for infrastructure-as-code configurations. Package managers store dependency information in JSON files. JSON is also prevalent in IoT devices, data analytics, and anywhere lightweight, structured data exchange is needed in modern technology stacks.
