[javascript] Is it possible to get all arguments of a function as single object inside that function?

The arguments object is where the functions arguments are stored.

The arguments object acts and looks like an array, it basically is, it just doesn't have the methods that arrays do, for example:

Array.forEach(callback[, thisArg]);

Array.map(callback[, thisArg])

Array.filter(callback[, thisArg]);

Array.slice(begin[, end])

Array.indexOf(searchElement[, fromIndex])

I think the best way to convert a arguments object to a real Array is like so:

argumentsArray = [].slice.apply(arguments);

That will make it an array;

reusable:

function ArgumentsToArray(args) {
    return [].slice.apply(args);
}

(function() {
   args = ArgumentsToArray(arguments);

   args.forEach(function(value) {
      console.log('value ===', value);
   });

})('name', 1, {}, 'two', 3)

result:

> value === name
> value === 1
> value === Object {}
> value === two
> value === 3
