### Code Explanation

#### Imports

- `import './App.css'`: This imports the CSS file `App.css` to style the components in this file.

- `import axios from "axios";`: Imports Axios library for making HTTP requests.

- `import { useEffect, useState } from "react";`: Imports `useEffect` and `useState` hooks from the React library.

#### Constants

- `const BASE_URL = "https://xxxxxxxxxxxxxxx.mockapi.io/v1/todo";`: Defines the base URL for the API endpoint.

#### Component Function

- `App`: This is the functional component named `App`.

#### State

- `const [data, setData] = useState(null);`: Initializes a state variable `data` using the `useState` hook, which will store the fetched data from the API.

#### useEffect Hook

- Utilizes the `useEffect` hook to perform side effects in the component.

- Fetches data from the API when the component mounts.

- Uses an empty dependency array (`[]`) to ensure the effect runs only once.

#### Fetching Data

- Defines an asynchronous function `fetchData` to fetch data from the API using Axios.

- Sets the fetched data into the `data` state variable.

#### Clean-up Function

- Defines a clean-up function inside the `useEffect` hook to cancel any pending Axios requests.

- This function is called when the component unmounts or re-renders.

- Helps prevent memory leaks by canceling pending requests before new effects are run.

#### JSX Return

- Renders JSX elements:

  - Heading `My Component to cancel useEffect`.

  - Unordered list (`
`) with three list items (`
`), each containing an anchor (``) tag with different links.

  - Displays the fetched data if available, using `JSON.stringify`.


#### Export

- `export default App`: Exports the `App` component as the default export from this file.
