Benchmark: forwardRef perf vs simple

HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.13.1/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.13.1/umd/react-dom.production.min.js"></script>
<div id="root-edu"></div>

Script Preparation code:

var people = [{a:1}, {a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1},{a:1}]
var root = document.getElementById('root-edu');

Tests:

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