    Try once with following code:

    const arr = [
  "2018-01-31",
  "65.56",
  "65.83",
  "64.55",
  "2018-02-28",
  "61.61",
  "62.31",
  "59.93",
  "2018-03-31",
  "61.87",
  "62.85",
  "60.26",
  "2018-04-30",
  "67.43",
  "68.39",
  "65.86",
];

const result = [];
for (let i = 0; i < arr.length; i += 4) {
  const date = arr[i];
  const icp = arr[i + 1];
  const slc = arr[i + 2];
  const dc = arr[i + 3];
  result.push({ date, icp, slc, dc });
}

console.log(result);

    Just use forEach and do some switch logic like this:

    const arr = ['2018-01-31','65.59','65.83','64.55','2018-02-28','61.61','62.31','59.93'];
let newArr = [];
let obj;
arr.forEach((data, index)=>{
  switch(index % 4) {
    case 0:
      obj = {date: data};
      break;
    case 1:
      obj.icp = data;
      break;
    case 2:
      obj.slc = data;
      break;
    default:
      obj.dc = data;
      newArr.push(obj);
  }
});
console.log(newArr);
