Now with the core basics and the foundation

about React and its most important features out of the way

and applied to our course project,

we're gonna take the next step in this module.

We're gonna have a look at three very important concepts

which you need to know as a React developer

and that will be effects, reducers and context.

Now these features are a little bit more advanced

which does not mean that they're difficult.

This just means you need know the other concepts first

which is why we are now diving into those concepts here

and with those features,

you will be able to make a huge step forward

towards more complex React applications.

Now in this module we will therefore take a closer look

at what effects are and how you can work

with so-called side effects which is what effects means,

but more on that in a second.

We'll have a look at how we can manage more complex state

in our components with reducers

and we will explore app-wide

or at least component-wide state so states that affect

multiple components with a concept called context

which is built into React to make sharing

state and state updates across components easier.

A lot of important features that are included here

so let's not waste any time and let's dive right in.
