Function.length: the number of declared arguments — ECMAScript v1
function.length
The length property of a
function specifies the number of named arguments declared when the
function was defined. The function may actually be invoked with more
than or fewer than this number of arguments. Don’t confuse this
property of a Function object with the length property of the Arguments object,
which specifies the number of arguments actually passed to the
function. See Arguments.length
for an example.
