Dosomethingargs

dosomethingargs is a term used in software design to describe a pattern where an operation is invoked with a single structured object that contains all the necessary parameters. It is not a formal standard, but a descriptive name that appears in code samples and tutorials to illustrate the practice of aggregating arguments into one argument, often called an args object. The name suggests a generic action, such as "do something," with its configuration conveyed through the arguments container.

In implementation, a function may be defined as dosomethingargs(args) or doSomethingArgs(params) in languages that prefer camelCase. The args object may include properties like target, options, mode, and callback. This reduces the need for long lists of positional parameters and makes it easier to provide defaults and to add new options without breaking existing calls. It is commonly used in languages that support object literals or dictionaries, such as JavaScript and Python, though the pattern appears in other ecosystems as well.

Design considerations include validation and type checking of args, handling missing or conflicting fields, and documenting the expected structure. Some implementations define a wrapper or factory to construct a validated args object; others rely on runtime checks. Pros include improved readability and forward compatibility; cons include the potential for runtime errors if properties are misspelled and reduced static type safety.

Related patterns include the options object pattern, the command pattern, and named parameter idioms. Dosomethingargs is typically discussed in material about function design and configuration objects, rather than as a formal API contract.
