multiparams

A multiparam is a term used in certain programming contexts, particularly in functional programming or languages that support flexible function definitions, to refer to a function that accepts multiple parameters. This is a fundamental concept in programming, as most functions are designed to operate on one or more inputs to produce an output. The specific implementation and handling of multiparams can vary significantly between programming languages.

In some languages, multiparams are simply individual arguments passed to a function, separated by commas. For example, a function `add(a, b)` takes two multiparams, `a` and `b`. Other languages might offer more sophisticated ways to handle multiple arguments, such as variable-length argument lists or parameter bundles. This allows for functions that can accept an arbitrary number of inputs, or that group related parameters together for clarity and organization.

The concept of multiparams is closely related to function arity, which is the number of arguments a function takes. A function with no arguments has an arity of zero, while a function taking one argument has an arity of one, and so on. Functions accepting multiple arguments are said to have an arity greater than one. Understanding how a particular language handles multiparams is crucial for writing correct and efficient code. This can involve syntax for defining functions with multiple parameters, rules for argument passing (e.g., by value or by reference), and mechanisms for dealing with optional or keyword arguments.
