Why can't I use a try block around my super() call?
A try block must have at least one catch clause or a finally block. .
Notice that the call to println() inside the try block is never executed.
Each try block or"throw" must have at least one corresponding catch block. .
The finally block is useful for cleaning up any resources allocated in the try block.
Each try block or"throw" must have at least one corresponding catch block. .
However, for Node 8.3+ the performance hit of calling a function inside a try block is negligible.
Once an exception has been thrown,control passes to the catch expression, and the try block is terminated.
For example, if you only do business in the U.S., try blocking all non-U.S. traffic for more protection.
Within the try block, only two of the three statements will execute: the first cout statement and the throw.

The nearest enclosing try block is inspected to see if it has a catch statement that matches the type of exception.
A try-catch statement may also be followed by finally,which executes regardless of whether or not the try block has completed successfully.
When control leaves the try block(for example due to a return, or just finishing normally), close(f) will be executed.
There are at least 3 places that the try block could fail, making this by far the cleanest way to handle errors in async code.
