In React, managing state is crucial for building dynamic and interactive user interfaces. The useState hook provides a simple and intuitive way to add state to functional components. Let's dive into the basics of `useState` and how to use it effectively.

**What is `useState`?**

useState is a hook in React that allows functional components to manage state. It takes an initial state as an argument and returns an array with two elements: the current state value and a function to update that value.

**How to use `useState`**

Using `useState` is easy. Here's a basic example:

```
import React, { useState } from 'react';
function ExampleComponent() {
const [state, setState] = useState(initialState);
return (
// JSX code
);
}
```

You can also add multiple state variables by calling `useState` multiple times:

```
function Form() {
const [name, setName] = useState('');
const [email, setEmail] = useState('');
return (

 setName(e.target.value)} placeholder="Name" />
 setEmail(e.target.value)} placeholder="Email" />

);
}
```

The `useState` hook makes it simple to add and manage state in functional React components. By understanding its basic usage, you can make your components more dynamic and interactive.

I remember this hook so well, when I first started using react, it gave me a lot of problems. Because I was very used to jquery e.t.c and could not understand how these states work at all.
As a matter of fact, I would import jQuery into react then to do basic things that ordinary react can do, just because of familiarity, now I look back at those days and simple smile!

@"dhtml"#p432 Oh wow, I didn't really learn jquery. One of the perks of being a senior developer.
