Convert array to object with key and value in javascript [duplicate]

Question

How covert or add array elements into object.

Now

arr = [
  ["1/1/2017",113],
  ["3/11/2017",58],
  ["3/12/2017",70],
  ["3/13/2017",76]
]

Should be

arr = [
  {date:"1/1/2017", count:113},
  {date:"3/11/2017", count:58},
  {date:"3/12/2017", count:70},
  {date:"3/13/2017", count:76}
]

Or even arr.map(([date, count]) => ({ date, count }));
