Hello John,
Good point. I started realize that this method
pushes the responsilibty for error handling up the chain,
which is something I sometimes struggle with
with if/else.
Once I really start writing some code, I'll be able
to see the benefits, as I'm sure I'll be happy with
these technique as well.

Error handling doesn't need to be part of your

Be careful saying that, especially to a newbie. While
experienced programmers presumably understand
statements other experienced programmers like you
make, a newbie might not understand an overly general
statement like the one you just made. I understand
what you are saying, but it is a gross simplification
for someone needing deep, penetrating understanding of
a new concept.
Error handling does not just magically disappear from
program logic, even if you use try/catch. In fact, it
is quite easy for code to fall prey to a Split Cleaner
bug pattern when using exception handling. Ken Downs
posted a "gotcha" with exception handling already.
Try/catch does not eliminate error handling from
program logic. Instead, it does only what it was
originally designed to do: let the caller of the
function determine how to respond to a failure
condition. Explicitly, the caller has greater
responsibility in the call chain, because the calling
function has more contextual knowledge and should be
more able to recover from failure gracefully.
