When working with the ReactDOM.render() method don't use its return value. It's considered deprecated and could be removed in the future. If you need to get the result of rendering, use a callback instead.
Bad practice
const app = ReactDOM.render(<App />, container);
doSomething(app);
doSomething(app);
Good practice
function doSomething(app) {
}
ReactDOM.render(<App ref={doSomething} />, container);
}
ReactDOM.render(<App ref={doSomething} />, container);
