5064 worker能够让js拥有多线程的能力，通过postMessage完成worker线程与宿主线程通信。
5067 接口实现详见：js_concurrent_module/worker
5071 宿主线程用于与worker线程通信的Object对象。
5084 通过判断存放worker.ts的workers目录是否与pages目录同级（以下简称目录同级）和创建项目的模型类别，共有以下四种新建Worker的方式：
5088 import worker from "@ohos.worker";
5089 const workerInstance = new worker.Worker("workers/worker.js", {name:"first worker"});
5093 import worker from "@ohos.worker";
5094 const workerInstance = new worker.Worker("../workers/worker.js", {name:"first worker"});
5098 import worker from "@ohos.worker";
5099 const workerInstance = new worker.Worker('entry/ets/workers/worker.ts');
5103 import worker from "@ohos.worker";
5104 const workerInstance = new worker.Worker('entry/ets/pages/workers/worker.ts');
5106 对于Stage模型中scriptURL——"entry/ets/workers/worker.ts"的解释：
5109 - worker.ts: 创建worker.ts文件或者worker.js文件都可以。
