Description:
Why is it that this "if err != nil {log.Fatal(err)}"
is used everywhere instead of a function call
to something that handles the error?

Comment 2:

In a very short program, as these examples are, it makes sense to exit when there is an
error.
In a larger program, one might return the error value to indicate to the calling code
that something went wrong.

Labels changed: removed restrict-view-owner.
