Why the output is not arguments

JavaScript
1

function args() { return arguments; }
args();

the reault is ?what’s the "return arguments; meaning?

2

‘arguments’ holds an array of the arguments given. Any number of arguments can be passed.

So for example, assuming the above function:

args(1, 2, 3);

would return an array containing the items 1, 2 and 3.

Say you have a function:

function countArguments(){
    return arguments.length;
}

Then:

alert(countArguments("Hello", "World", "3.14159265358979323846", "Hello again"));

Would output 4, because 4 arguments are passed to it.

The function args and countArguments wouldn’t have any real-life use, but I suppose its a theory thing. Realistically a function would use the arguments variable in someway, rather than returning it.
