Code has errors but still am successful


Why am I able to proceed if my code is not providing the desired and required results?
1.I want to see what I am doing wrong
2. why am I successful if I clearly have a broken code that does not show my desired result


I can't even get the course to load


What browser are you using


currently chrome. I need to interchange between chrome and firefox as my typing/backspace does not line up with cursor
