• Create Components folder under src folder
• Add FetchDataExp1.js file and add below Code

import React, { Component } from "react";

const API = "https://hn.algolia.com/api/v1/search?query=";

const DEFAULT_QUERY = "redux";

class FetchDataExp1 extends Component {

constructor(props) {

super(props);

this.state = {

hits: []

};

}

componentDidMount() {

fetch(API + DEFAULT_QUERY)

.then(response => response.json())

.then(data => this.setState({ hits: data.hits }));

}

render() {

return (

<div>

<ul>

{this.state.hits.map(hit => (

<li key={hit.objectID}>

<a href={hit.url}>{hit.title}</a>

</li>

))}

</ul>

</div>

);

}

}

export default FetchDataExp1;

• Open index.js file and update code as below

function App() {

return (

<div className="App">
