+};														
+

+//Although, we still can change a property’s value if it’s an object:

+frozenObject.address.street = 'React'; // no error, new value is set
+
+
+delete frozenObject.name // Cannot delete property 'name' of #<Object>
+
+
+//We can check if an object is frozen by using
+Object.isFrozen(obj) //true
