All language subtitles for 015 Tapping Into Context with the useContext Hook_en

So lets explore the useContext Hook.

For that here,

I will actually remove

this code, I will

remove to Consumer.

Like this.

And therefore I'm back to my

old navigation Component

but of course now

I'm referring to that

CTX object which simply

doesn't exist anymore.

Now we are still importing

AuthContext, and we can

use it again.

Now by importing a

Hook from React,

and that's the useContext Hook.

Another Hook that's built into React.

And it does what the name implies,

it allows us to use the Context,

it allows us to tap into a Context

and listen to it.

Using it is simple,

you call useContext in your React Component Function,

and you pass the Context appointer at

the Context you want to use to it.

So in our case, I'm pointing to AuthContext.

Now what you get back, is the Context value.

So here...

I'll store this in a CTX Constant

to make my code down there worth again.

And with that,

we can save this.

And it will again, work just fine.

Simply, because I'm using the useContext Hook.

Easy like that.

Simple like that.

This is all we need to do

and this, of course

I would say it's a bit more

elegant and a bit nicer

than using AuthContext Consumer,

which you...

However, just to make this clear,

are always allowed to use.

It's not wrong or anything like that.

This is just a bit more elegant

in my opinion.
