How to handle if i got multiple events unable to m dates in multiple array

[unaveen]

I was unable to display the multiple event dates on the calendar.
My data is coming with multiple arrays for each date.
If i have got this output lwith multiple arrays like this then it highlights only one date (last date15-10-2020),

##output coming like this:

["2020-10-21"]
0: "2020-10-21"
length: 1
__proto__: Array(0)

["2020-10-22"]
0: "2020-10-22"
length: 1
__proto__: Array(0)

["2020-10-14"]
0: "2020-10-14"
length: 1
__proto__: Array(0)

["2020-10-15"]
0: "2020-10-15"
length: 1
__proto__: Array(0)

##Expected Output is:

// calendar init
  var eventData = [
    { date: "2020-10-09", badge: false, title: "Example 1" },
    { date: "2020-10-04", badge: false, title: "Example 2" },
    { date: "2020-10-24", badge: false, title: "Example 3" },
    { date: "2020-11-07", badge: false, title: "Example 4" },
  ];
  $("#my-calendar").zabuto_calendar({
    data: eventData,
  });
