Pliki probne JSON

JavaScript Object Notation (.json) files represent structured data as nested objects and arrays in a language-agnostic, human-readable format. Integral to REST APIs, configuration files, and data interchange, JSON’s ubiquity demands robust tooling. Use sample .json files to test schema validation, serialization/deserialization loops, large-payload streaming, and front-end data binding, covering nested structures, mixed types, and special characters.
