The developer console in Chrome gives you more than just the location of
the "throw" statement: you get a complete stack trace. Just expand the
error message by clicking the little arrow icon to the left.

Collapsed view:

  [x] > Uncaught Error: Something went wrong          included.js:2

Expanded view:

  [x] v Uncaught Error: Something went wrong          included.js:2
        badFunc                                       included.js:2
        (anonymous function)                          test.html:13

In this example, the function badFunc() in included.js throws the Error,
and it was called in test.html, line 13.
