Building Applications with React Native

# What are hooks?
Hooks can be thought of as a way to tap into features of React using a simple syntax.

A **hook** enables us to use features such as state, lifecycle methods, and other features of React, without having to write a lot of code.

These are the most common hooks used in React Native:
- `useState`
- `useEffect`
- `useContext`
- `useReducer`
- `useMemo`
- `useRef`

> Hooks can only be used in functional components. 

We’ll look at the useState hook in this lesson. As we progress through the course, we’ll look at other hooks.

# The `useState` hook
This is the most common hook used in React Native. It is used to create and manage the state of your application.

## Syntax

```js
const [state, setState] = useState(initialState);
```
Here, `state` is the actual value of the state and `setState` is a function we can use to update the state. We do not need to define the `setState` function. It is created to update the `state` variable. The `initialState` parameter is the initial value of the state.

# Example
Let's create a simple counter using the `useState` hook.
