Don't use the return value of the 'ReactDOM.render()' method

When working with the 'ReactDOM.render()' method don't use its return value

CheckId RCT010111
TypeName ReactDOMRenderRule
Severity Warning
Type TypeScript file

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);

Good practice
function doSomething(app) {

ReactDOM.render(<App ref={doSomething} />, container);
