**Hello Developers 👋**, 

It’s me your friend [Md Taqui Imam](https://mdtaquiimam.vercel.app), and today I’m going to explain a new and exciting hook in React called **useActionState**.

_[Follow me in Github⭐](https://github.com/taqui-786)_

## What is useActionState?

useActionState is a new React hook that helps us update state based on the result of a form action.

It’s like a smart helper that remembers things for us and can change them when we submit a form.

**_[Checkout Official Documentation🚀](https://react.dev/reference/react/useActionState)_**

> Important Note: Right now, useActionState is only available in React’s Canary and experimental channels. To get the most out of it, you’ll need to use a framework that supports React Server Components.

## How to use useActionState?

To use this hook, we first need to import it from React:

import { useActionState } from 'react';
Then, we can use it in our component like this:

```
const [state, formAction, isPending] = useActionState(actionFunction, initialState);
```
**Here’s what each part means:**

**‘state’** is our current form state
**‘formAction’** is a new action we’ll use in our form
**‘actionFunction’** is the function that runs when the form is submitted
**‘initialState’** is the starting value of our state

## When to use useActionState:

Use this hook when you want to update state based on form submissions, especially if you’re using Server Components and want quicker responses.

**Example:**

Let’s make a simple counter form using useActionState:

```
import { useActionState } from "react";

async function increment(previousState, formData) {
  return previousState + 1;
}

function StatefulForm() {
  const [state, formAction] = useActionState(increment, 0);
  return (
    <form>
      {state}
      <button formAction={formAction}>Increment</button>
    </form>
  );
}
```
**In this example,** every time we click the button, our count goes up by one. The useActionState hook takes care of updating the state when the form is submitted.

## That’s it 😅
Remember, the best way to learn is by doing.

So when **useActionState** becomes more widely available, give it a try in your projects and see how it can improve your forms!
