Menu
I've made this React app but i keep getting this error:
Uncaught Error: createRoot(...): Target container is not a DOM element.
Can someone help me please? This is my index.html and index.js.
<!DOCTYPE html>
<html lang="en">
<head>

<div id="root"></div>
</body>
</html>
import React from "react";
import ReactDOM from "react-dom/client";
import App from "./App";
import reportWebVitals from "./reportWebVitals";
ReactDOM.createRoot(
<React.StrictMode>
<App />
</React.StrictMode>,
document.getElementById("root")
);
reportWebVitals();
I've already tried every possible solutions that are uploaded to the internet, but unfortunately non of them hasn't worked yet.

As the docs say, the signature is:
ReactDOM.createRoot(rootNode).render(<App />);
And it replaces:
ReactDOM.render(<App />, rootNode)
So you need to change your code to
ReactDOM.createRoot(
document.getElementById("root"),
)
.render(
<React.StrictMode>
<App />
</React.StrictMode>,
);
