What is JSON Schema Validation?
JSON Schema is a vocabulary for defining the structure, content, and semantics of JSON data. A JSON Schema validator checks whether your data conforms to a given schema definition. JSONKit uses the Ajv library for fast, spec-compliant validation with detailed error messages pointing to exact locations of violations.
