Fnc to split array in numbered batches

Split Array in Equal Batch

  function splitPayload(arr, batchSize) {
    let tempArr = arr;
    let result = [];
    let rest = arr.length % batchSize; // number of non divisble elements
    let partLength = Math.floor(tempArr.length / batchSize); // number to divide remaining number of array element
    let restData = tempArr.splice(0, rest)
    result.push(restData)
    for (let i = 0; i < partLength; i++) {
      let restData = arr.splice(0, batchSize)
      result.push(restData);
    }
    return result;
  }
