Ajv

AJV (Another JSON Validator) is a tool used by developers to ensure that data in JSON format adheres to specific rules or structures. Think of it as a spell checker for data; it verifies that the data follows certain patterns, like required fields or data types, before being used in applications. This helps prevent errors, ensure data consistency, and improve reliability in software systems. AJV is fast, flexible, and widely used for validating data in web applications and APIs.
