ParamArrays in JavaScript functions possible?

[Water Cooler v2]

Can javascript functions have variable number of arguments - a concept
known as paramarrays?

The arguments object is a local variable. Referencing it via the
function object is (as I recall) deprecated.

Could you give a better alternative, please?

Thanks, Evertjan. So, internally, functions are objects, just like in
python. Cool.

....name would smell just as sweet (or, something like that; from Romeo
& Juliet, right?). Thanks!

You can simply do e.g.
for (var i = 0; i < arguments.lengt h; i++)
in any function to loop through the arguments passed in. Doing
functionName.ar guments
instead of simply
arguments
is deprecated.

Objects? I do not think you should conclude this out of my words.

It seems that sum.arguments is outdated and just arguments works fine.

=============== ===============

However jscript 5.6 specs shows this:

function ArgTest(a, b){
var numargs = arguments.lengt h; //Get number of arguments passed.
var expargs = ArgTest.length; //Get number of arguments expected.
[.....]

.... introducing ArgTest.length as the length of the specified/expected
arguments, new to me!

Functions are objects in JavaScript, that is right, but certainly not
only "internally ", whatever "internally " means exactly.

Thanks, see my other post for functionName.le ngth.
