js 冒泡排序实现

const arr = [1, 5, 4, 7, 9, 3, 6, 8, 0, 2]

const bubb = (arr) => {
  for (let i = 0; i < arr.length - 1; i++) {
    for (let j = 0; j < arr.length - 1 - i; j++) {
      if (arr[j] > arr[j + 1]) {
        let temp = arr[j]
        arr[j] = arr[j + 1]
        arr[j + 1] = temp
      }
    }
  }
  return arr
}
console.log('arr1', bubb(arr))//arr1 (10) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
