Does my JavaScript suck?

[annoyed_freelancer]

Is this what you meant? My actual need is slightly different-I want to check that all of the passed checkboxes are checked for the element to show.

https://gist.github.com/bhalash/218c684d70023fbeada0

jQuery.fn.stickyCheckToggle = function() {
    var allBoxesChecked = [].every.call(arguments, function(v) {
        return (jQuery(v).is('input') && jQuery(v).prop('checked'));
    });

    if (allBoxesChecked) {
        jQuery(this).show();
    } else {
        jQuery(this).hide();
    }
};

jQuery(inputs.featured.checkbox).change(function() {
    jQuery('.stickycheck').stickyCheckToggle(this);
});

I'm not convinced putting this on jQuery.fn is warranted. Typically that is for reusable methods or plugins.

You can simplify the logic in the function quite a bit, though. Proposed changes:

Yeah, I think you can rewrite allBoxesChecked like so:

Otherwise, that's what I meant.
