Decorators

Decorators (supported by Babel)

If you’re using something like mobx, 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.

Non-decorators approach

class ProfileContainer extends Component {
  // Component code
}
export default observer(ProfileContainer);

With decorators

@observer
export default class ProfileContainer extends Component {
  // Component code
}
