React Sort HoC

Sort.jsx

import React from 'react';
import { Component } from 'react';

let Sort = Sortable => class extends Component {
    constructor(props) {
        super(props);

        this.state = {
            items: []
        }
    }

    componentWillReceiveProps(nextProps) {
        this.updateSort(nextProps);
    }

    componentDidMount() {
        this.updateSort(this.props);
    }

    updateSort({items, reverse, comparator}) {
        let _items = [...items];

        _items.sort(comparator);
        if (reverse)
            _items.reverse();

        this.setState({items: _items});
    }

    render() {
        return (
            <Sortable {...this.props} items={this.state.items} />
        );
    }
}

Sort.propTypes = {
    items: React.PropTypes.array.isRequired,
    reverse: React.PropTypes.bool,
    comparator: React.PropTypes.func
}

Sort.defaultProps = {
    reverse: false,
    comparator: Sort.lessThan
}

Sort.lessThan = (l, r) => r < l;
Sort.lessThanOrEqual = (l, r) => r <= l;
Sort.greaterThan = (l, r) => r > l;
Sort.greaterThanOrEqual = (l, r) => r >= l;

// byProperty supports dot notation for nested objects, like `person.city.name`
Sort.byPropertyWithComparator = (p, c) => (l, r) => c(p.split('.').reduce( (o,i) => o[i], l), p.split('.').reduce( (o,i) => o[i], r));
Sort.asNumberWithComparator = (c) => (l, r) => c(parseFloat(l), parseFloat(r));
Sort.asStringWithComparator = (c) => (l, r) => c(l.toString(), r.toString());

export default Sort;

Great!!!

Hey it would be cool if you could provide some example usage, greatly appreciated :)
