Object.entries(person) returns: [["firstName","John"],["lastName","Doe"],["email","[email protected]"]]
We can use an ES6 'for-of' loop to interate over it. Each iteration gets an
array where the 0th index is the property name and the 1st index is the
value. We can use ES6 array destructuring to directly extract the values
into separate variables.

console.log(key + ' ' + value);
