Objects: Merging two objects into one

To merge two simple objects into one you can use the spread operator in this way:

const object1 = {
  name: 'Flavio'

const object2 = {
  age: 35

const object3 = {...object1, ...object2 }

Notice that if both objects have a property with the same name, then the second object property overwrites the first.

Also note that if properties of the object are not primitive types, only their reference is copied, not the object.
