Axios

Axios is a Javascript library that use promise-based HTTP client designed for Node.js and browsers. so, we can easily send asynchronous HTTP requests to REST APIs and perform create, read, update and delete operations (CRUD). It is an open-source collaboration project hosted on Github. It can be imported in plain Javascript or with any library accordingly. 

Promise-based: Programming paradigm that uses promise object to handle asynchronous operation.

To install Axios open terminal and write the following command.

npm i axios

    useEffect(()// Constructor
    constructor(props) {
        super(props);
        this.state => {
            items: [],
            DataisLoaded: false,
        };
    }
 
    // ComponentDidMount is used to
    // execute the code
    componentDidMount() {
        axios.get(
