I have been following javascript tutorial from http://www.w3school.com and while reading one of the examples i have got one question in my mind, the code is as follows:

<html>
<body>

<script type="text/javascript">

 var txt =new String ("Hello World!");
 document.write(txt.constructor);

 </script>

</body>
</html>

Now, iam getting in response of this code is :

function String() { [native code] }

However, according to me the constructor must have a parameter in it somewhat like this:

function string(value){}

Can anybody please tell me why it is returning the constructor with no parameter.

    Even no parameter defined in a JavaScript function, we still can get the parameters with arguments:

    function test() {
  console.log(arguments);
}

test(1,3,6); // Output "[1,3,6]" in console.
