摘要：
创建新工作人员。js文件，并编写一个worker子线程脚本。代码如下：constworkercode=（）=˃{self.onmessage=function（e）{console.log（'Messagereceivedfrommainscript'）；varworkerResult='Receivedfrommain:'+（e.data）；console.log（'Postingmessage
新建一个worker.js文件，编写worker子线程脚本，代码如下：
const workercode = () => {
self.onmessage = function(e) {
console.log('Message received from main script');
var workerResult = 'Received from main: ' + (e.data);
console.log('Posting message back to main script');
self.postMessage(workerResult); // here it's working without self
}
};
// 把脚本代码转为string
let code = workercode.toString();
code = code.substring(code.indexOf("{")+1, code.lastIndexOf("}"));
const blob = new Blob([code], {type: "application/javascript"});
const worker_script = URL.createObjectURL(blob);
module.exports = worker_script;
按照上述方式，创建好worker_script，在react项目组件中引用时只需要在对应的组件文件中：
import worker_script from './worker';
var myWorker = new Worker(worker_script);
myWorker.onmessage = (m) => {
console.log("msg from worker: ", m.data);
};
myWorker.postMessage('im from main');
