JSX & Conditional Rendering in ReactJS

Updated App.js File:

App.js


import React, { Component } from 'react';

const element = <h1>Simple JSX Example</h1>;

function ConditionalComp({ condition }) {
    if (condition) { return <p>Condition is true</p>; } else { return <p>Condition is false</p>; }
}

function ConditionalCompType2({ condition }) {
    return condition ? <p>Condition is true</p> : <p>Condition is false</p>;
}

function logicalANDComp({ isLoggedIn }) {
    return isLoggedIn && <p>Welcome!</p>;
}

class DynamicComp extends Component {
    constructor(props) {
        super(props);
        this.state = { isAuthenticated: false };
    }

    render() {
        return this.state.isAuthenticated ? <p>Welcome!</p> : <button onClick={() => this.setState({ isAuthenticated: true })}>Login</button>;
    }
}

function App() {
    return (<div><DynamicComp /></div>);
}

export default App;
