break:跳出循环,执行循环外的代码

continue:跳出本次循环,执行下一次的循环

举个例子:

javascript">let num = 0
    for (let i = 0; i < 10; i++) {
      for (let j = 0; j < 10; j++) {
        if (i == 5 && j == 5) {
          break
        }
        num++
      }
    }
    console.log(num);//95

javascript">let num = 0
    for (let i = 0; i < 10; i++) {
      for (let j = 0; j < 10; j++) {
        if (i == 5 && j == 5) {
          continue
        }
        num++
      }
    }
    console.log(num);//99
