I assume you are asking, "Why do these features exist? What makes them
useful? When would I use them?"

For that, you should re-read the documentation and discussion
surrounding them. The short answer is that the above makes your job,
as a programmer easier. It's easier because you have to write less
code, read less code, and your code has fewer bugs.
