reactjs - React loop over an object with array - 


data = [   {     "2017-08-09": [       "09:00",       "09:30",       "10:00",       "10:30",       "11:00",       "11:30",       "13:00",       "13:30",       "14:00",       "14:30",       "15:00",       "15:30",       "16:00",       "16:30"     ]   } ]

i'm trying map on array of objects , display info follows: 

date 2017-08-09  available hours    09:00   09:30   10:00        ...

i'm having trouble looping on data structure,

i've updated link. did not use lodash, nested map() calls. first map through initial array, , within each object grab keys of object. after that, map through keys of object, , 1 last map() through times of each date.

you can refer below code: 

const data = [    {      "2017-08-09": [        "09:00",        "09:30",        "10:00",        "10:30",        "11:00",        "11:30",        "13:00",        "13:30",        "14:00",        "14:30",        "15:00",        "15:30",        "16:00",        "16:30"      ]    }  ];    class app extends react.component {    render() {      return (        <div>          <h2>js map</h2>          {            data.map(item => {                            return object.keys(item).map(date => {                return (                  <div>                    <h1>{date}</h1>                    {item[date].map(time => {                      return <h3>{time}</h3>                    })}                  </div>                )              })            })          }        </div>      );    }  }    reactdom.render(<app />, document.getelementbyid("root"));
