Status update

[GeekyHacks]

In this PR I did the following:

• Added the updateStatus class which updates the status of completed property inside the task object and gives you access to delete completed tasks
• Fixed linter errors

Optional suggestions

Every comment with the [OPTIONAL] prefix won't stop the approval of this PR. However, I strongly recommend you to take them into account as they can make your code better. Some of them were simply missed by the previous reviewer and addressing them will really improve your application.

Cheers, and Happy coding!👏👏👏

Feel free to leave any questions or comments in the PR thread if something is not 100% clear.
