Although try/catch is useful, it is only applicable to imperative code: try showButton(); catch (exception) /... Error bounds maintain React's declarative nature and operate as you'd expect.

The try... catch... finally statement defines a code block to try, as well as a response in the event of an error. The try statement begins with one or more try blocks and finishes with one or more catch and/or finally clauses.

Yes, we can declare a try-catch block inside another try-catch block, which is known as nested try-catch.

Try/catch blocks separate error-handling code from programme code, making it easier to discern a program's logical flow. Details of the actions to be taken when an exception occurs are not included in the logic in the programme code. The catch blocks provide such information.

If an exception is thrown in the try -block, the catch -block contains sentences that define what to do. Control is immediately shifted to the catch -block if any statement within the try -block (or a function called from within the try -block) throws an exception.
