Chrome Dev Tools last line debugging before script ends, is it possible?

Question

JavaScript

Situation:
A large project in which the element is no longer displayed, the script simply exits either on an exception or on a return, or generally ends its work with nothing. I researched for 4 hours, found in the middle of the code return on the condition ...
Task:
So it's quite easy to debug an exception in Chrome, if this is the end of the script, by and large, you can put a debugger;
And how to find out if it was returned for example return?
But, more importantly, Chrome has a pause on the first line of the script, is it actually possible to pause before the end of the script in order to analyze previous calls?
