title: How to find source of JS_Parse_Error?
body: <p>I am running an Express app, and I am getting a JS_Parse_Error. I cannot figure out why. I have basically commented out all of the new code that I've written, yet I am still getting the error. Is there a way to find out what Javascript line is giving me the error?</p>
