In mathematics and in computer programming, a variadic function is a function of indefinite arity, i.e., one which accepts a variable number of arguments.Support for variadic functions differs widely among programming languages.
In mathematics, an argument of a function is a value provided to obtain the function's result. It is also called an independent variable. [1]For example, the binary function (,) = + has two arguments, and , in an ordered pair (,).
Variables (and expressions thereof) from the calling context can be arguments: if the subroutine is called as a = 2; b = 3; add(a, b) then the variables a, b are the arguments, not the values 2, 3. See the Parameters and arguments section for more information.

A helper function is a function which groups parts of computation by assigning descriptive names and allowing for the reuse of the computations. [6] Although not all wrappers are helper functions, all helper functions are wrappers, and a notable use of helper functions—grouping frequently utilized operations—is in dynamic binary translation, in which helper functions of a particular ...
These are typically built into browsers, in their DevTools window. Debuggers allow you to step debug (go through your JavaScript code line-by-line, hover over variables to see their values, etc.) Firefox - use Tools → JavaScript Console showing all JavaScript and CSS errors. Chrome and Edge - use Tools → Developer Tools.

A function call using named parameters differs from a regular function call in that the arguments are passed by associating each one with a parameter name, instead of providing an ordered list of arguments. For example, consider this Java or C# method call that doesn't use named parameters:
