-: So I've been saying multiple times now
that we need a better error-handling strategy, right,
and so now it's time to finally build it.
And error handling is a really important aspect
of any backend application,
which is the whole reason why error handling
even got its own section in this course.
So, in this section, I'm gonna show you
how we can use Express and environment variables
to build quite a robust error-handling workflow
that you can then use for your own applications
in the future.
