Thank you for the contribution. It has been approved.

@aymenz I liked how you spent the entire video tutorial working on the count down function. You explained each step and provided learners with some alternate ideas, such as count up.

It is very important to explain why and how each concept works. This will give learners a complete understanding of the concepts you are teaching so they can apply it to their own projects.
