ParamName

ParamName is a placeholder commonly used in technical documentation and example code to denote the name of a parameter. It is not a real identifier in a specific language but a stand-in used for illustration when describing how functions, methods, or interfaces receive input.

In programming, parameter names appear in function or method signatures and in API definitions. The choice of the actual identifier replaces ParamName in real code. Using a descriptive and consistent parameter name helps convey the parameter’s purpose and the data it represents.

Naming conventions for parameters vary by language and project. ParamName itself demonstrates a common style in documentation rather than a recommended form. In JavaScript, parameter names often use camelCase (paramName), while Python tends toward snake_case (param_name). In strongly typed languages like Java or C#, parameter names are typically descriptive and may reflect the type or role, such as limit or userId.

In APIs, parameter names are used in query strings, headers, or path templates. Clear, stable names improve readability and usability. It is important to avoid reserved words, maintain consistency across endpoints, and consider the difference between path parameters and query parameters. Documentation should clarify what the parameter represents and its expected values.

Best practices include choosing meaningful names that reflect the parameter’s role, keeping names concise, avoiding abbreviations that are not widely understood, and documenting any effects or constraints. For boolean flags, prefixing with is or has can improve clarity. Consistency within the project reduces confusion for developers consuming functions or APIs.
