如何按规则拆分数组块？

function splitArrayByRule(arr, rule) {
  let result = [];
  let chunk = [];

  for (let i = 0; i < arr.length; i++) {
    chunk.push(arr[i]);

    if (rule(chunk)) {
      result.push(chunk);
      chunk = [];
    }
  }

  if (chunk.length > 0) {
    result.push(chunk);
  }

  return result;
}

// 示例用法
const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
const rule = (chunk) => chunk.length === 3; // 拆分规则为每个子数组长度为3

const result = splitArrayByRule(arr, rule);
console.log(result); // [[1, 2, 3], [4, 5, 6], [7, 8, 9], [10]]
