And that's it for this module.

Now you learned that React is able to talk to a backend

but not to a database directly

for a security and performance reasons.

But you can send requests to backend APIs

very often that will be rest APIs like we see it here.

And then you can, for example, use the fetch API

or a third-party libraries like X,

yes to perform that request.

And to then also get the response, analyze the response

and maybe throw and generate an error if it's needed

and or work with the data you get back

as part of the response.

You learned how you can send both get and post requests.

And you also learned how you can handle different States

which are involved with sending requests.

A loading and an error State.

And the we have no data State

as well as the we do have data State.

All of that is important

and allows you to build rich user experiences

which you want to have in most

of your applications of course,

because sending HDP requests is a crucial task.

And here in this demo, you learned how it generally works.
