<!DOCTYPE html> <html> <body> <h1>JavaScript Statements</h1> <h2>The const Statement</h2> <p>Declaring a constant object does NOT make the properties unchangeable:</p> <p id="demo"></p> <script> // Create an object: const car = {type:"Fiat", model:"500", color:"white"}; // Change a property: car.color = "red"; // Add a property: car.owner = "Johnson"; // Display the property: document.getElementById("demo").innerHTML = "Car owner is " + car.owner; </script> </body> </html>
