import React from 'react';
import './BusinessList.css';

import Business from '../Business/Business';

class BusinessList extends React.Component {
  render() {
    return (
      <div className="BusinessList">
        {
          this.props.businesses.map(business => {
            return <Business business={business} key={business.id} />
          })
        }
      </div>
    );
  }
}

export default BusinessList;

我一直在尝试解决未定义的映射，尽管我没有取得任何实际进展。这里有人至少有一个想法可以帮我解决吗？提前谢谢了
