+Pool implements the `Iterable` interface, you can use `for...of` to iterate.
+At the same time, `Pool` also implements the `AsyncIterable` interface, you can use `for await...of` to iterate asynchronously.
+
+```javascript
+// Iterate over the resources in the resource pool, and get the resources at the same time,
+// When iterating synchronously, if there are no resources in the resource pool, the iteration will exit
+for (const resource of pool) {
+  console.log(resource.id);
+}
+
+// When iterating asynchronously, if there are no resources in the resource pool, it will wait for the resources to be acquired
+// So when iterating asynchronously, it will not exit the iteration, which is equivalent to an infinite loop
+for await (const resource of pool) {
+  console.log(resource.id);
+}

+
+### PromiseLike
+
+Pool implements the `PromiseLike` interface, you can use `await` to wait.
+
+```javascript
+// await pool means waiting for all resources to be released before returning

+### Iterable
+
+Pool 实现了 `Iterable` 接口，可以使用 `for...of` 进行遍历。
+同时 `Pool` 也实现了 `AsyncIterable` 接口，可以使用 `for await...of` 进行异步遍历。
+
+```javascript
+// 遍历资源池里边的资源，同时会获取资源，
+// 同步遍历时，如果资源池中没有资源，会退出遍历
+for (const resource of pool) {
+  console.log(resource.id);
+}
+
+// 异步遍历时，如果资源池中没有资源，会等待资源的获取
+// 所以异步遍历时，不会退出遍历，相当于一个无限循环
+for await (const resource of pool) {
+  console.log(resource.id);
+}
+```
+
+### PromiseLike
+
+Pool 实现了 `PromiseLike` 接口，可以使用 `await` 进行等待。
+
+```javascript
+// await pool 意味着等待所有资源都被释放，才会返回
+await pool;

 ### pLimit / Pool.limit
 
 是的，`cat5th/pool.js` 很贴心的提供了一个 `pLimit` 和 `Pool.limit` 的方法，它是`Pool.prototype.limit`的别名。
