Name

Function.arguments[] — arguments passed to a function

Availability

JavaScript 1.0; JScript 1.0; ECMAScript v1; deprecated by ECMAScript v3

Synopsis

                  function.arguments[i] 
function.arguments.length

Description

The arguments property of a Function object is an array of the arguments that are passed to a function. It is only defined while the function is executing. arguments.length specifies the number of elements in the array.

This property is deprecated in favor of the Arguments object. Although ECMAScript v1 supports the Function.arguments property, it has been removed from ECMAScript v3 and conforming implementations may no longer support this property. Therefore, it should never be used in new JavaScript code.
