Chrome Dev Tools and Script Execution View
I want to know when a resource is executing JavaScript. In WPT it appears easy to see when the script is executing by the horizontal line in the waterfall. How is this done in Dev Tools? I suspect that when you run the performance test in Chrome, the yellow scripting bar indicates execution?

I'm trying to determine if a script is synchronous or asynch and it seems that if the script executes after DOMCONTENTLoaded then it is DEFER. Is there an easy way to determine this in Dev tools? I suspect that per this article, any script that loads after the DOMCONTENTLoaded is synchronous?
