Add a Property Based on Two Existing Properties

Given an object with 'firstName' and 'lastName' properties, add a new property called 'fullName' whose value is the two properties joined with a space.

const person = { firstName: 'Ada', lastName: 'Lovelace' };
 
// Add a 'fullName' property below, combining firstName and lastName

 
console.log(person.fullName); // expected: "Ada Lovelace"
