on channel: Coding with Elyaas

These examples demonstrate how to manage properties inside a JavaScript object. The first code shows how to remove an existing property using the delete keyword and what happens when you try to access a property that does not exist (it returns undefined). The second code shows how to add a new property to an object dynamically and successfully retrieve its value. Together, they explain how JavaScript objects can be modified after creation.
