I dislike how try / catch is used for control flow logic, especially as JS / TS natively do not tell you at the type level, that this is the case: E.g.: As you can see, QuokkaJS knows at runtime this thunk is throwing, but as you can see in the pop-over, the type system ...
Flow of control in try catch finally in Java: To summarise everything we have learned so far: If exception occurs in try block then control immediately transfers(skipping rest of the statements in try block) to the catch block. Once catch block finished execution thenfinally blockand after tha...

as far as the Try / Catch control flow goes, I never quite understood the need for a "Finally" statement; if you have a Catch statement, why not just move the contents of the "Finally" statement to after the body of the Try / Catch block?
we should use try-except or try-catch block. Also we should try to avoid using try-catch or try-except blocks for flow control. Only if-else blocks should be used for flow control. Also, while performing file handling operations, we must use try-except block. Stay tuned for more informa...
When control reaches an await in the async method, progress in the method is suspended until the awaited task completes. When the task is complete, execution can resume in the method. For more information, seeAsynchronous Programming with Async and Await (C# and Visual Basic)andControl Flow in...
If the implementation of the try block changes, will your control flow still behave as expected? If the answer to one or more of these questions is 'no', there might be a lot of forgiveness to ask for; most likely from your future self. An example. I recently saw...
Control flow can never reach a Catch block that follows either of these variations.The type is Exception, for example: Catch ex As Exception The statement has no exception variable, for example: Catch When a Try…Catch…Finally statement is nested in another Try block, Visual Basic first ...

You specify the statements that might throw exceptions inside a TRY block. If any of the statements within the TRY block encounters an error, the control flow is transferred to the first statement inside the CATCH block. On the contrary, if none of the statements inside a TRY block raise an...
