JavaScript problem (draw function and more)

Question

Hello,
Me and my partner are currently having a problem with the game we are making. The game character is not showing up on the screen and we have a problem with checking whether the character is in the array and if not, what should we write in the code to make the character be in the array. Any advice???
Thank you in advance.

Thank you very much!!! This helped us a lot. My partner and I are only 14 years old by the way and we are at the beginning of our programming career.
