re: Use $ & $$ Instead of document.querySelector/All in JavaScript without jQuery VIEW POST

FULL DISCUSSION
 

This is my take on it. It checks whether I'm asking for an id or not, and if I am, it returns just that one element. If not, the NodeList is made into an array.

const $ = (q, d = document) => 
  /#\S+$/.test(q)                       // check if query asks for ID
  ? d.querySelector.bind(d)(q)          // if so, return one element
  : [...d.querySelectorAll.bind(d)(q)]  // else, return all elements in an array.
