Under Construction

This section is incomplete, please see the old docs for React.PureComponent.

React.PureComponent is similar to React.Component. The difference between them is that React.Component doesn’t implement shouldComponentUpdate(), but React.PureComponent implements it with a shallow prop and state comparison.

If your React component’s render() function renders the same result given the same props and state, you can use React.PureComponent for a performance boost in some cases.

class Welcome extends React.PureComponent {
render() {
return <h1>Hello, {}</h1>;
