Exercise 1

// 1. Create a new object called person, with a firstName key and a lastName key
// Put your first and last name as values to those keys

// 2. Log the firstName key using dot notation

// 3. Log the lastName key using bracket notation

// 4. Freeze the object you created above

// 5. Try and change an attribute on the object. If you don't see the expected behavior, make the necessary fix so that the freeze method works.
