//The in operator returns true if the specified property is in the specified object or its prototype chain.

const car = { make: 'Honda', model: 'Accord', year: 1998 };

console.log('make' in car);
// expected output: true


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;
};
