// set hash value(s)
hash.set({
  age: 5
});
 
// set more hash values
hash.set({
  color: 'blue'
});
 
// get hash query string object
console.log(hash.get()); // => { age: 5, color: 'blue' }
 
// replace whole hash
hash.replace({
  age: 7
});
 
console.log(hash.get()); // => { age: 7 }
 
const handler = () => {
