The slider JS code doesn't work without the main one (true programmers pls)

I would like to use the slider as a “component”. Accordingly, I need only the slider code. I found it — here it is:

function(t, e, r) {
    "use strict";
    var n = r(14),
        i = r(167),
        a = {
            ARROW_LEFT: 37,
            ARROW_UP: 38,
            ARROW_RIGHT: 39,
            ARROW_DOWN: 40,
            SPACE: 32,
            ENTER: 13,
            HOME: 36,
            END: 35
        },
        s = 'a[href], area[href], [role="button"], input, select, textarea, button, iframe, object, embed, *[tabindex], *[contenteditable]';
    n.define("slider", t.exports = function(t, e) {
        var r, o, l, h = {},
            c = t.tram,
            u = t(document),
            f = n.env(),
            p = ".w-slider",
            d = '<div class="w-slider-dot" data-wf-ignore />',
            m = '<div aria-live="off" aria-atomic="true" class="w-slider-aria-label" data-wf-ignore />',
            v = "w-slider-force-show",
            y = i.triggers,
            g = !1;

        function E() {
            (r = u.find(p)).length && (r.each(x), l || (b(), n.resize.on(_), n.redraw.on(h.redraw)))
        }

        function b() {
            n.resize.off(_), n.redraw.off(h.redraw)
        }

        function _() {
            r.filter(":visible").each(F)
        }

        function x(e, r) {
            var n = t(r),

            i || (i = t.data(r, p, {
