I updated after reading your feedback about keeping class based components and add function component version in detail. class Greeting extends React.Component {
render() {
return <div>Hello {this.props.message}</div>;
}
}
ReactDOM.render(
<Greeting message="World" />,
document.getElementById("root")
);Functional component versionconst Greeting = ({ message }) => {
return <div>Hello {message}</div>;
};
ReactDOM.render(
<Greeting message="World" />,
document.getElementById("root")
);You can write the same code without JSX as below, class Greeting extends React.Component {
render() {
return React.createElement("div", null, `Hello ${this.props.message}`);
}
}
ReactDOM.render(
React.createElement(Greeting, { message: "World" }, null),
document.getElementById("root")
);Functional component versionconst Greeting = ({ message }) => {
return React.createElement("div", null, `Hello ${message}`);
};
ReactDOM.render(
React.createElement(Greeting, { message: "World" }, null),
document.getElementById("root")
); |

@0xprincedev Those are legacy questions. That's why I used the same class component. |

I updated class based components to functional components for question 83:
Is it possible to use react without JSX?
