This code snippet will output 1:
(function (params) {
console.log(params);
}(1, 2));
The params object has replaced the default arguments. Can we retrieve the original arguments object within the function's scope?

According to Matt's comment earlier, the answer is "no", which seems to be correct. However, you can always consider using a similar approach like this:
(function myFunction(parameters) {
console.log(myFunction.parameters);
}(1));
This should work in Firefox, and possibly in other browsers as well since it follows standard behavior. But if you're hesitant to change the name of your function's argument, then you might also be reluctant to assign a name to your function too?
(Please note that the above code snippet still represents a function expression rather than a declaration. Even though it's no longer anonymous, you still cannot access myFunction outside its scope.)
Upon further reflection, it is indeed possible!
(function (params) {
(function () {
console.log(params.callee.caller.arguments);
})();
})(1, 2);
