JSON

JSON (JavaScript Object Notation): A lightweight, language-independent data format for structured data interchange, built on universally supported key-value pairs and ordered arrays.

JSON is the standard for modern data exchange, leveraging human-readable text to transmit structured information. Its minimal syntax uses two core types: objects (unordered collections of name:value pairs, like {"user": "alpha"}) and arrays (ordered lists of values, like [1, 2, 3]). This structure, derived from JavaScript, ensures efficient parsing and generation across all major programming languages (e.g., Python, Java, Go). We deploy JSON extensively: it is the de facto payload for RESTful APIs and the preferred format for application configuration files (e.g., package.json). The current specification (RFC 8259) ensures consistent, high-scale interoperability.
