按值将数组拆分为数组数组

function splitArrayByValue(arr, value) {
  return arr.reduce((result, element) => {
    if (element === value) {
      result.push([]);
    } else {
      result[result.length - 1].push(element);
    }
    return result;
  }, [[]]);
}

const arr = [1, 2, 3, 4, 1, 5, 6, 1];
const value = 1;
const result = splitArrayByValue(arr, value);
console.log(result);
