How to optimize an application that receives properties and a re-render array of components?

class App extends React.Component {
    render() {
        const { current, items } = this.props;
        return(
            <div>
                { items.map(({ id, value }) => (
                    <div style={ { backgroundColor: (id === current.id ? 'cyan' : '') } }
                         key={ id }>
                        { value }
                    </div>
                ))}
            </div>
        );
    }
}

const items = [{ id: 1, value: 'A' }, { id: 2, value: 'B' }];
const current = items[0];
ReactDOM.render(<App items={ items } current={ current } />, document.getElementById('root'));
