Error using JS AutoSave and Loop in HTML

Hi, I have saved a django field using javascript before and it has worked perfectly. However, I have never done this when trying to loop through filtered data in my HTML. This causes an error at this line in my javascript:

Uncaught SyntaxError: unexpected token: identifier:
Line: let autosaveTimer;

Does anyone have any guidance about how I can remedy this? The code works perfectly when I don’t loop through data in my HTML. All code is below.

# Create your models here.
