Server side Code:

• Use catch

Answer 1

I don't think try/catch blocks are always appropriate for low-level methods. You want to catch (and log/alert, even better!) any errors before they get to the user, of course. But it is often better for a low-level method to just lets its errors get raised up to a higher level. The problem I have seen with low-level error trapping is that it often lets a larger operation continue, but then a result that is not quite correct gets presented to the user or saved to the database, and in the long run it's much more difficult to fix. It's also just a lot of extra clutter in your code to put a try/catch at every level if you're not going to "do anything" with the error until it's raised up to a higher level.
