Default Parameters
Default parameters are a programming language feature that allows function parameters to have predefined values if no argument is provided or if the argument is undefined. This helps simplify function calls by reducing the need for explicit checks for missing arguments and providing sensible fallback values. It is commonly supported in modern programming languages like JavaScript, Python, and C++.
Developers should use default parameters to write cleaner, more robust code by handling missing inputs gracefully without verbose conditional logic. This is particularly useful in functions with optional arguments, such as configuration settings, API calls with optional parameters, or utility functions where sensible defaults exist. It improves code readability and reduces the risk of errors from undefined values.
