How to trace error in Custom Script

Hi,
I have done some changes in my custom script and while creating a new record, I am getting this error on form load.

What is the way to trace this error, I mean how I would know that which line number or statement is creating error?

Seems like a syntax error - ’ Unexpected token )’. for debugging you can use exception handling as well as adding console.log wherever necessary.
