Hi,
I’m reading the Getting started with React atricle.
Just in the beginning of the Interrogating the index section there is a desription about src/index.js
Instead of this line of code:
ReactDOM.render(<App />, document.getElementById('root'));
I got this:
ReactDOM.render(
<React.StrictMode>
<App />
</React.StrictMode>,
document.getElementById('root')
);
just notifying…
