import {
isMainThread,
BroadcastChannel,
Worker,
} from 'node:worker_threads';
const bc = new BroadcastChannel('hello');
if (isMainThread) {
let c = 0;
bc.onmessage = (event) => {
console.log(event.data);
if (++c === 10) bc.close();
};
for (let n = 0; n < 10; n++)
new Worker(__filename);
} else {
bc.postMessage('hello from every worker');
