JSON Patch
JSON Patch is a format for describing changes to a JSON document, defined in RFC 6902. It uses a JSON array of operations (like add, remove, replace, move, copy, and test) to specify modifications, enabling efficient and partial updates without transmitting the entire document. This is commonly used in APIs, configuration management, and collaborative editing systems to synchronize JSON data.
Developers should learn JSON Patch when building RESTful APIs or systems that require partial updates to JSON resources, as it reduces bandwidth and improves performance by sending only the changes. It's particularly useful in real-time applications, version control for JSON configurations, and scenarios like PATCH HTTP requests in web services, where atomic and idempotent updates are needed.
