Overwriting arguments object for a Javascript function
- by Ian Storm Taylor
If I have the following:
// Clean input.
$.each(arguments, function(index, value) {
arguments[index] = value.replace(/[\W\s]+/g, '').toLowerCase();
});
Would that be a bad thing to do? I have no further use for the uncleaned arguments in the function, and it would be nice not to create a useless copy of arguments just to use them, but are there any negative effects to doing this?
Ideally I would have done this, but I'm guessing this runs into problems since arguments isn't really an Array:
arguments = $.map(arguments, function(value) {
return value.replace(/[\W\s]+/g, '').toLowerCase();
});
Thanks for any input.
EDIT: I've just realized that both of these are now inside their own functions, so the arguments object has changed. Any way to do this without creating an unnecessary variable?
