react/no-render-return-value Correctness

This rule will warn you if you try to use the ReactDOM.render() return value.

Using the return value from ReactDOM.render() is a legacy feature and should not be used.

Note that ReactDOM.renderhas been removed entirely in React 19 and so should generally not be used.

Examples of incorrect code for this rule:

jsx

var inst = ReactDOM.render(<App />, document.body);
function render() {
  return ReactDOM.render(<App />, document.body);
}

Examples of correct code for this rule:

jsx

ReactDOM.render(<App />, document.body);
