Description With objects, there is a difference between having two references to the same object and having two different objects that contain the same properties. Examples let object1 = {value: 10}; let object2 = object1; let object3 = {value: 10}; console.log(object1 == object2); // true console.log(object1 == object3); // false object1.value = 15; console.log(object2.value); // 15 console.log(object3.value); // 10 `const` objects can have their values changed const score = { visitors: 0, home: 1 }; score.visitors = 23; console.log(score); // { visitors: 23, home: 1 }
