Is there any way to select all items in an array without using a loop?

[Snookerman]

I want to go through all checkboxes (all inputs are checkboxes) on a page and uncheck them if they are checked. This is what I came up with:

checkboxes = document.getElementsByTagName('input');
for (var index = 0; index < checkboxes.length; index++){
checkboxes[index].checked = false;
}
My first instinct was to just do one of these:

checkboxes = document.getElementsByTagName('input');
checkboxes.checked = false;
//or
checkboxes[all].checked = false;
That of course doesn't work, but is there any other way to do something to all items in an array without using loops? Thanks!

My instincts tell me no. The "way" would involve still looping through each whether or not you look at it. You could write a function called "dotoarray()" something like array_map() in PHP, but I'm not sure how that would be helpful.
There may be some trick, though.

After some looking around, I found two methods, forEach and map, that look like they might help here, but I've no idea how. I still have a lot to learn.

Isn't foreach like in PHP, then? And I expect map() is like array_map() in PHP. The effect with both though is that you are actually using a loop-- it's just not part of the code that you write. For processing speed, etc., I expect it would be the same.
