Hello! This is my first time posting assessment here. Please help me assess my work. Thank you! 😀

Hi @harvey25115 and welcome to the community 👋

Congratulations! All three tasks are correct 🏅

If you like to post more assessments in the future it would be really helpful for us if you put your code into an online editor and post the link. It is much easier for us to assess your work if we see running code and can test different things out.  
Also please make sure to add a link to the task page on MDN.  
You will find these instructions at the bottom of all task pages. For example: [Assessment or further help | MDN](https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Objects/Test_your_skills:_Object-oriented_JavaScript#assessment_or_further_help)

Thank you and have fun coding 🙂  
Michael
