All you know that arguments is a special object that holds all the arguments passed to the function.
And as long as it is not an array - you cannot use something like arguments.slice(1).
So the question - how to slice everything but first element from arguments?
UPD:
seems like there is no way without converting it to an array with
var args = Array.prototype.slice.call(arguments); If someone posts another solution it would be great, if not - I'll check the first one with the line above as an answer.

javascript - How does args. slice(1) separate the arguments that are passed into PhantomJS and forEach(function(arg, i)...
The arguments. length property contains the number of arguments passed to the function.
There are two ways to pass arguments to a function: by reference or by value. Modifying an argument that's passed by reference is reflected globally, but modifying an argument that's passed by value is reflected only inside the function.
Q. How to slice everything but first element from arguments?
The following will return an array containing all arguments except the first:
var slicedArgs = Array.prototype.slice.call(arguments, 1); You don't have to convert arguments to an array first, do it all in one step.
