How to get a slice from arguments

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.

Meddling with array functions is not actually necessary.

Using rest parameter syntax ...rest is cleaner and more convenient.

Example

function argumentTest(first, ...rest) {

  console.log(First arg: + first);



  // loop through the rest of the parameters

  for (let arg of rest) {

    console.log(-  + arg);

  }

}



// call your function with any number of arguments

argumentTest(first arg, #2, more arguments, this is not an argument but a contradiction);

...Rest
