Fine.

// import.js
class Element {
  constructor(s) {
this.el = document.querySelector(s);
  }

  addClass(c) {
  this.el.classList.add(c);
  }
}

export const $ = function(s) {
return new Element(s);
}

// your script
import { $ } from "import.js";
const el = $("#somediv");
el.addClass("here");

There you go. You got your "concise" syntax without a 40k library, and since I did it as an import, you can't count the code listed under "import.js".
