In this example, a variable is left undefined, so console.log generates an exception. The try bracket is used to contain the code that encounters the exception, so the application does not crash. The catch block is skipped if the code works. But, if an exception occurs, then the error i...

Common scenarios that require exception handling include: User input: Exceptions can occur when code processes user input. For example, exceptions occur when the input value is in the wrong format or out of range. Data processing and computations: Exceptions can occur when code p...

Is this a known issue for the existing exception handling that will be fixed? I don't have a test case outside of our real code that I can share - is it worth my time to work on a test case that I can share or is this already known and will be addressed (I don't want to ...
