const originalObj = { name: 'John', age: 34 }
let newObj = { ...originalObj, city: 'New York' }
// newObj is now { name: 'John', age: 34, city: 'New York' }

// it can also be used with the same object
newObj = { ...newObj, language: 'en' }
// { name: 'John', age: 34, city: 'New York', language: 'en' }
