Outro to React Hooks 

[00:00] You did it! All right, that's the end. Well done. Look at all the stuff that we did. We got this stuff working super well. Look at that derived state. It's magic. It updates the URL. You refresh and you still got it. Super, super cool. You can click on these hearts and they are very happy to see you.

[00:19] And you learned all about the React app lifecycle, initial render, creating the DOM, user interact, state changes, re-render, update the DOM. You know what this does and what this represents and how React manages to give you a nice declarative API where you don't have to think about time. Time still matters and data changing over time, that still matters,

[00:39] but you don't have to think about it. React manages it for you in a way that really scales really nicely, as proven by the decade that we've been doing this. It's awesome. More now. Then we also have this useEffect stuff where we fixed things with the dependency.

[00:56] This also worked and you saw what the heck is going on here. That was super fun, right? And then we learned all about the hook flow and how things operate over time between the mount, update, and unmount cycles. Pretty interesting to understand that.

[01:12] And then we went pretty deep on interacting with local storage and doing side effects and updating state over time. All of this stuff I think was super interesting and fun. I'm glad that you joined me for this workshop learning about the basic React hooks. I hope that you take this knowledge

[01:29] and make some excellent user experiences on the web using React. Thanks for joining me. See ya.

In this workshop, we'll learn how to use hooks to manage state, synchronize side-effects, generate unique ids, and more. 

**You'll get a solid understanding of the basic hooks and how to use them.**

We'll be covering these hooks: 

- useState
- useEffect
- useRef
- and useId

At the end of the workshop you'll put everything you learned together and build a Tic Tac Toe game with game history saved in local storage!

## Managing UI State

React's App Lifecycle: Initial Render → Create the DOM → User Interacts → State Changes → Re-render → Update the DOM → Repeat.

Here, you'll be learning how to use the `useState` hook and about the cycle of user interaction, state changes, and re-rendering. The core of how React works!

## Side-Effects

In this section, you'll learn about the `useEffect` hook.

`useState` is for component state, and `useEffect` is for managing side-effects (things that happen outside our react components).

Things outside our react components include:

- Browser APIs like local storage, geolocation, media devices, etc.
- Integrations with third-party libraries like D3, Chart.js, etc.


## Lifting State

A common question from React beginners is how to share state between two sibling components. 

The answer is to "lift the state!" 

But, sometimes you'll find yourself in the opposite situation, where you have state that's lifted too high and doesn't need to be shared. So, in this section, you'll also be learning how to "colocate state."

## DOM Side-Effects

Sometimes, you need to update the DOM directly, like if you're needing a library that interacts with the DOM or ar dealing with focus management. 

To do this you'll learn about how to use both the `ref` callback and the `useRef` hook. 

## Unique IDs

Form input elements need to have globally unique `id` attributes. But, you're also building reusable components in React. 

How do you make sure that you're getting unique IDs?

In this section, you'll solve this problem with the `useId` hook.

## Tic Tac Toe

Here's where it all comes together!

You'll practice all the skills you learned over the course of this workshop by building a Tic Tac Toe game with game history that gets perserved in local storage. 

It's tougher than the other exercises. But, after you get through it, you'll have really solidified everything you learned.

Learn React hooks to add interactivity to your apps and build dynamic websites. You'll learn the core React hooks including useState, useEffect, and useRef.
