Need to display only the Column Name's containing in each row of an array

Eg: From the console

```
this.GobalTableDataSets
(3) [{…}, {…}, {…}]
0: {centerName: "--", batchName: "MentorSchedule_5D5C", scheduleStartDate: "20-Nov-2019 14:38:17", scheduleEndDate: "20-Dec-2019 14:38:17", …}
1: {centerName: "--", batchName: "MentorSchedule_2657", scheduleStartDate: "20-Nov-2019 10:29:46", scheduleEndDate: "20-Dec-2019 10:29:46", …}
2: {centerName: "--", batchName: "Enroll_cf845bd8-43", scheduleStartDate: "18-Jul-2019 18:32:00", scheduleEndDate: "31-Jul-2019 21:28:00", …}
length: 3

```

**component.ts**

```
this._liveDashboardService.getBatchDetails(orgReqDetailsEx ).subscribe(response => {
   if (response !== null && response.length > 0 && response !== null) {
          this.batchDetails = response;
   }
});

```

**Expected Result:**

```
this.GobalTableDataSets[0].<someFunction>
"centerName"
"batchName"
"scheduleStartDate"
"scheduleEndDate"

```

***Here the requirement is to console only the Column Name's (all or particular name) containing from an above array of each row, but not necessarily displaying/fetching Column Values containing those respective Column Name's from an array***

Are there any built-in functions from Angular to accomplish the above scenario?
