Feedback on my Blackjack Code

Hello!

I created a blackjack game using only javascript, html, and css. I decided to start this project to practice prototypal inheritance. I am looking for feedback on my coding. How would you clean this up? How would you structure it differently? Did you find any bugs?

I am still trying to figure out how to write cleaner code. I assume this code is not the most readable and I apologize.

Thank you for any help! Here is the JSFiddle of the project. https://jsfiddle.net/mikeonthejob/jkycmv60/2/

Also, I have not started the code for splitting your cards. I still need to figure out how to add that without a code rewrite...however, that may be the only option.

Note: My local machine has images loading for the face cards. I could not find a way to load that resource into JS Fiddle.
