Unexpected end of input, need help, important project, cant find the unexpected end of input in code, :(

i was using Google chrome to check the errors of this project (javascript page) and it said

"Uncaught SyntaxError: Unexpected end of input gamepad.js:36"

the problem is, i cant seem to find the error on the line, is there any way of checking? like a spell check or something that can do code? il post the line of doe anyway so maybe you can just check it,

thanks in advance anyway if its fixed or not,
