I'm new to ReactJS.
I'm trying to display Hello world
using the code below, but I get this error message:
What am I missing?
Code for App.js
//App.js`
import React from 'react';
const App = () => "<h1>Hello World!</h1>";
export default App;
Code for index.js
//index.js
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
ReactDOM.render(
<App />,
document.getElementById('root')
);
Code for /public/index.html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>React App</title>
</head>
<body>
<div id="root"></div>
</body>
</html>
You can't wrap a JSX element in quotes.
Change this
const App = () => "<h1>Hello World!</h1>";
by this
const App = () => <h1>Hello World!</h1>;
You can also write it like this
const App = () => {
return <h1>Hello World!</h1>;
};
Or like this
const App = () => {
return (
<h1>
Hello World!
</h1>
);
};
You can also write it this way and avoid the return statement.
Notice the absence of curly braces, it took me some time to notice they were simple parentheses.
const App = () => (
<h1>
Hello World !
</h1>
)
