Answer 1

i never heard of location.href("somefile.php");... location.href = "somefile.php"; is the "normal" way that you should use.

Answer 2

1. href is not a method, it is a property whose value is a string.
2. The first is a call on a method with a url as the argument (incorrect), the second is assigning the url as the value of the property (correct).
