const menuWrapper = document.querySelector(".portfolio-menu");

if (menuWrapper !== null) {
  const [all, lovers, chef, girl, guy, grandmother, granddad] = [
    ".all",
    ".lovers",
    ".chef",
    ".girl",
    ".guy",
    ".grandmother",
    ".granddad",
  ].map((selector) => {
    return menuWrapper.querySelector(selector);
  });

  const menuElems = menuWrapper.querySelectorAll("li");
}

Может-ли быть пустой JS на 1 Гб?

.element {
  position: absolute;
  left: 0;
  transition: ease opacity .5s, ease left 0s;
  transition-delay: 0s, 0s;

  &:not(.is-active) {
    left: -99999px;
    opacity: 0;
    transition-delay: 0s, 0.5s;
  }
}
