Look this following image
According to the image, it will first try the try block, if it finds an error, it will go to the catch block, passing an argument (error or err or even e) are the parameters most often used by developers, where it passes the error's StackTrace.
You can pass a different stacktrace, if you notice in the else statement there is a "throw new Error()"; this is the one that will be responsible for giving a custom stacktrace.
Anyway, I hope I clarified your questions about Try/Catch statements, and this is my first post here ;)
See you
