Benchmark: seperate getcookie vs all cookies (with decode)

Script Preparation code:

function getCookies(str) {
  str = str || document.cookie;
  var reKey = /(?:^|; )([^=]+?)(?:=([^;]*))?(?:;|$)/g;
  var cookies = {};
  var match;
  var cnt = 0;
  while ((match = reKey.exec(str))) {
    cnt += 1;
    reKey.lastIndex = match.index + match.length - 1;
    var k = match[1];
    var v = decodeURIComponent(match[2]);
    if (!!cookies[k]) {
      if (typeof cookies[k] == "string") {
        cookies[k] = [cookies[k]];
      }
      cookies[k].push(v);
    } else {
      cookies[k] = v;
    }
  }
  !!!cnt && (cookies = undefined);
  return cookies;
}
// make the multiple values of the cookie into a comma delimitted string
function all(str) {

  let cookies = getCookies(str);
  if (!!cookies) {
    if (!!cookies["BGC_AUT_LVL"]) {

      }
    }
  } else {
    cookies = {};
  }
  return cookies;
}

function getCookie(name) {
  var nameEQ = name + "=";
  var ca = document.cookie.split(";");
  for (var i = 0; i < ca.length; i++) {

    while (c.charAt(0) == " ") c = c.substring(1, c.length);

      var d = c.substring(nameEQ.length, c.length);
      d = decodeRFC(d);
      return d;
    }
  }
  return undefined;
}

function decodeRFC(s) {
  s = s + "";
  return s.replace(/\*/gm, "##").replace(/##/gm, ",").replace(/!/gm, " ");
}
