Hi Jakob, Thank you for replying!
To be more specific, I'm looking for the point (function) that initiate the compilation process. In my understanding, when handling an "event", the renderer process in the browser will figure out the JavaScript related to the event, and ask the V8 engine to execute it by calling some api function. Inside those api function, there should be a point where V8 initiate the compilation process, and that is what I'm looking for.
