All language subtitles for 001 Module Introduction_en8

It's time to practice what we learned,

because thus far over the last modules,

we learn a lot about React.

We learn a lot about the core

features that make up React.

And you actually already have enough knowledge

to start building your first simple React projects.

To specifically practice these

super important core concepts we covered thus far,

I get a dedicated project

for which I want to go with you,

which is relatively simple

but which picks up all these

core things you've got to know.

We're going to build this relatively simple,

yet not too simple, application here.

It's application where you can add

fictional users like Max

you can enter an age and add a user.

Now you won't be able to edit or delete the user

but we've got a couple of other nice features

which we haven't built thus far

but which we actually will be able to build.

For example, if I have my empty inputs here

and I click on add user,

you see I get this warning dialogue,

this warning overlay here,

which we can dismiss by clicking on, okay

or by clicking on the backdrop.

You will also see that if I enter

let's say a negative age here,

I get a different error message.

So we got a little bit of a more complex validation

and we of course got this modal component.

This overlay here, which is something,

you know from a lot of web pages as well.

Last but not least, if you add a user successfully

we also reset these inputs here.

So that also works.

So while it's certainly not the most

complex application of the world,

it is a great project for practicing

what we learned thus far.

You can absolutely skip this module

if you're not interested in that

and you just want to continue to the next concepts

to the next things you need to learn about React.

But I would recommend that you go

through this module to make sure you really

understand all those core concepts we

worked on over the last modules.

And I actually encourage you to go ahead

and try this on your own first.

You of course don't have to get the exact styling right.

Instead it is about building these React components

and adding the general logic

I showed you over the last minutes.

Of course this will be challenging,

but you will only need concepts and features

you learned about so you can build this.

But again, it definitely will be challenging.

Nonetheless, definitely give this

a try on your own first.

But of course thereafter

have a look at my course lectures

in this section where I show you

my approach and my solution

which you can then use to compare your solution.
