Learn React Hooks: useReducer - Simply Explained!

In this video we will learn about React hooks, starting with useReducer. This powerful React hook will allow you to enhance how you manage and mutate state in your React application. You will learn the difference between useReducer and useState, how to create your reducer function, how to define your actions and return a mutated copy of the state in your application.

In this new React world, hooks are here to stay, so it's best to learn them! In this tutorial I demonstrate the useReducer React hook, and I explain it very simply and in a way that is easy to understand. Enjoy!

I just want to say that these react hooks videos are by far the best and easiest to understand. They are fantastic for new devs and senior devs just getting into react. 😊

This series on React hooks has been super informative. Really appreciate this content, these may be the best explanation videos I have ever watched, for any language.

It's important to understand the strictness of immutability is enforced. If you don't return a new object in your reducer the component will not re-render. This is a bit different if you're coming from redux-toolkit. Redux toolkit will give you a brand new object in your reducers. Great video

1:28 to 1:48, just summarization and I already got what it does. I did not use it really, but used redux, so it absolutely made sense. Thanks!

Darius, This is great,

Thank you so much for these contents you put out, i just joined the discord and i am excited about what you have on there, it is really mind blowing...

I want to suggest if you can make a YT short video, to talk about sample scenarios when it's is suitable to use useReducer instead of useState.

I feel this might clarify things better for Jr react devs like me.

Thank you.
