How you use decorators in React?

You can decorate your class components, which is the same as passing the component into a function. Decorators are flexible and readable way of modifying component functionality.

class Profile extends React.Component {
title is a string that will be set as a document title
WrappedComponent is what our decorator will receive when
put directly above a component class as seen in the example above
const setTitle = (title) => (WrappedComponent) => {
return class extends React.Component {
componentDidMount() {
document.title = title;
render() {
return <WrappedComponent {...this.props} />;

Note: Decorators are a feature that didn't make it into ES7, but are currently a stage 2 proposal.
