isObjectEmpty.js

// The below source code performs 20 times faster than the one line version
const isObjectEmpty = (object) => {
  if (object.constructor !== Object) return false;
  // Iterates over the keys of an object, if
  // any exist, return false.
  for (_ in object) return false;
  return true;
};

// one line version
const isEmpty = obj => Reflect.ownKeys(obj).length === 0 && obj.constructor === Object;

Check Whether the Object is Empty
