One of the laziest EL implementations, but with cache

el.js

export const el = (nodeName, props = {}, children = []) => {
  const $el = (el.cache[nodeName] || (
    el.cache[nodeName] = document.createElement(nodeName)
  )).cloneNode(true);
  Object.assign($el, props).append(...children);
  return $el;
};
el.cache = {};
