Description

Contains the number of arguments a function is defined with.

Syntax

functionname.length

The functionname argument is required and is the name of the function in question.

Remarks

The length property of a function is initialized by the scripting engine to the number of arguments in the function's definition when an instance of the function is created.

What happens when a function is called with a number of arguments different from the value of its length property depends on the function.
