Enough about databases for now but let's stick to storing data and let me dive into some mechanisms
of storing data in memory or even on the client side,
so in the browser. And for that in this module, we'll have a look at the sessions and cookies,
two important constructs or technologies in web development in general which you can of course also
use in nodejs. Now in this module, we'll have a look at what exactly cookies are
and of course what exactly sessions are and then how you can use both and how you typically use them
together.
So let's dive in and let's understand what these things are and how we can add them to our project and
why we would add them.
