jQuery code snippet: loop through the element, but not including the last element

The following jQuery code snippet loops through all <select></select> elements on the page, adds their values ??to an array, and then uses the .concat() function to concatenate these values ??into a string. This code will not process the last <select></select> element. The last element can be excluded using the .not(":last") selector.

var controlitems = $('select').not(':last'); // Exclude the last select element
var controlfilters = [];

controlitems.each(function(i, v) {
    var filtervalue = $(this).val();
    if (filtervalue !== "") {
        controlfilters.push(filtervalue);
    }
});

console.log([].concat(controlfilters));

output will be an array containing all <select></select> elements values ??(except the last one).
