Parameter Handling
Parameter handling is a fundamental programming concept that involves managing the input values passed to functions, methods, or procedures in code. It includes techniques for defining, validating, processing, and passing parameters to control program behavior and data flow. This concept is essential across all programming languages and frameworks for building robust and maintainable software.
Developers should master parameter handling to write clean, error-resistant code and implement features like function overloading, default values, and input validation. It is critical in scenarios such as API development (handling query parameters, request bodies), configuration management, and building reusable libraries where flexible and secure input processing is required.
