Tests:

Component With forwardRef

Normal component
const ComponentWithoutForwardRef = (props) => ( React.createElement('div', null, // Your component content 'Component without forwardRef' ) ); var benchmarkTest = () => { ReactDOM.render(React.createElement(ComponentWithoutForwardRef), root); }; benchmarkTest();
Normal with list
const ComponentWithForwardRef = React.forwardRef((props, ref) => ( React.createElement('div', { ref: ref }, 'Component using forwardRef' ) )); const App = () => ( React.createElement('div', null, people.map((person, index) => ( React.createElement(ComponentWithForwardRef, { key: index }) )) ) ); ReactDOM.render(React.createElement(ComponentWithForwardRef), root);
