for 循环打印 1~5
能筛出偶数
while 循环能倒数

// 任务1：for 打印 1 到 5
for (let i = 1; i <= 5; i++) {
  console.log(i);
}

console.log("---");

// 任务2：for 打印 1 到 10 的偶数
for (let i = 1; i <= 10; i++) {
  if (i % 2 === 0) {
    console.log(i);
  }
}

console.log("---");

// 任务3：while 从 10 倒数到 1
let n = 10;
while (n >= 1) {
  console.log(n);
  n--;
}

- [x] for 循环打印 1~5 - [x] 能筛出偶数 - [x] while 循环能倒数 ```ts // 任务1：for 打印 1 到 5 for (let i = 1; i <= 5; i++) { console.log(i); } console.log("---"); // 任务2：for 打印 1 到 10 的偶数 for (let i = 1; i <= 10; i++) { if (i % 2 === 0) { console.log(i); } } console.log("---"); // 任务3：while 从 10 倒数到 1 let n = 10; while (n >= 1) { console.log(n); n--; } ```
