# React State and Styling

**What is useState?**

* `useState` is a built-in Hook in React that allows you to manage and update the state of a component.
* State is essentially data that can change over time within your component.

**How does it work?**

1. **Import the Hook:**

   JavaScript

   ```jsx
   import React, { useState } from 'react';
   ```
2. **Declare State Variable:**

   JavaScript

   ```jsx
   const [count, setCount] = useState(0); 
   ```

   * `count`: This is the name of your state variable (you can choose any name).
   * `setCount`: This is a function that you'll use to update the value of `count`.
   * `0`: This is the initial value of `count` (you can set it to any value).
3. **Use State Variable and Update Function:**

   JavaScript

   ```jsx
   <button onClick={() => setCount(count + 1)}>Click me</button>
   <p>You clicked {count} times</p>
   ```

   * The `onClick` handler calls the `setCount` function to increment the `count` by 1.
   * The `p` tag displays the current value of `count`.
