jQuery Get value from class attribute of multiple elements in array without loop

Question

I have multiple Select dropdown elements with a single class .select

<select class='select' name='select1' id='select1'>
  <option value='1'>1</option>
  <option value='2'>2</option>
  <option value='3'>3</option>
</select>

<select class='select' name='select2' id='select2'>
  <option value='4'>4</option>
  <option value='5'>5</option>
  <option value='6'>6</option>
</select>

<select class='select' name='select3' id='select3'>
  <option value='7'>7</option>
  <option value='8'>8</option>
  <option value='9'>9</option>
</select>

I know it can be achieved with the help of loop like this

var arr = [];
$('.select').each(function () {
   arr.push($(this).val());
});

But I already have so many loops in the code and I'm wondering if is there any way it can be achievable without a loop

No, there's no other way to get the value from multiple elements, you have to iterate over the elements to get the value from each of them.

There are other ways to write basically the same code

var arr = $.map($('.select'), function (el) { return el.value; });

or without jQuery

var elems = document.querySelectorAll('.select'),
    arr   = [];

for (var i=elems.length; i--;) arr.push(elems[i].value);

but they all iterate, there's no other way to do that.
