上述代码中，setTimeout函数模拟了一个异步操作，并在1秒钟后随机生成一个数字。如果随机数大于0.5，则执行resolve回调函数并将随机数作为参数传递；否则执行reject回调函数并传递一个错误对象作为参数。 上述代码中，setTimeout函数模拟了一个异步操作，并在1秒钟后随机生成一个数字。如果随机数大于0.5，则执行resolve回调函数并将随机数作为参数传递；否则执行reject回调函数并传递一个错误对象作为参数。

### 注意事项
- 仅支持在Stage模型且module的compileMode为esmodule的project中使用taskpool api。确认module的compileMode方法：查看当前module的build-profile.json5，在buildOption中补充"compileMode": "esmodule"。
- taskpool任务只支持引用入参传递或者import的变量，不支持使用闭包变量，使用装饰器@Concurrent进行拦截。
- taskpool任务只支持普通函数或者async函数，不支持类成员函数或者匿名函数，使用装饰器@Concurrent进行拦截。
- 装饰器@Concurrent仅支持在ets文件使用。

Actor并发模型的交互原理：各个Actor并发地处理主线程任务，每个Actor内部都有一个消息队列及单线程执行模块，消息队列负责接收主线程及其他Actor的请求，单线程执行模块则负责串行地处理请求、向其他Actor发送请求以及创建新的Actor。由于Actor采用的是异步方式，各个Actor之间相互隔离没有数据竞争，因此Actor可以高并发运行。 Actor并发模型的交互原理：各个Actor并发地处理主线程任务，每个Actor内部都有一个消息队列及单线程执行模块，消息队列负责接收主线程及其他Actor的请求，单线程执行模块则负责串行地处理请求、向其他Actor发送请求以及创建新的Actor。由于Actor采用的是异步方式，各个Actor之间相互隔离没有数据竞争，因此Actor可以高并发运行。
### 注意事项
- Worker存在数量限制，当前支持最多同时存在8个Worker。
- 在API version 8及之前的版本，当Worker数量超出限制时，会抛出错误Error "Too many workers, the number of workers exceeds the maximum."。
- 从API version 9开始，当Worker数量超出限制时，会抛出错误BusinessError "Worker initialization failure, the number of workers exceeds the maximum."。
- 主动销毁Worker可以调用新创建Worker对象的terminate()或workerPort.close()方法。
- 自API version 9版本开始，若Worker处于已经销毁或正在销毁等非运行状态时，调用其功能接口，会抛出相应的BusinessError。
- Worker的创建和销毁耗费性能，建议管理已创建的Worker并重复使用。
- 创建Worker工程时，new worker.Worker构造函数和new worker.ThreadWorker构造函数不能同时使用，否则将导致工程中Worker的功能异常。自API version 9版本开始，建议使用[new worker.ThreadWorker](#constructor9)构造函数，在API version 8及之前的版本，建议使用[new worker.Worker](#constructordeprecated)构造函数。
- 创建Worker工程时，在Worker线程的文件中（比如本文中worker.ts）不能导入任何有关构建UI的方法（比如ets文件等），否则会导致Worker的功能失效。排查方式：解压生成的Hap包，在创建Worker线程的文件目录中找到"worker.js"，全局搜索"View"关键字。如果存在该关键字，说明在worker.js中打包进去了构建UI的方法，会导致Worker的功能失效，建议在创建Worker线程的文件中修改 "import “xxx” from src"中src的目录层级。
- 线程间通信时传递的数据量最大限制为16M。
