```cjs
const cluster = require('cluster');

// Go through all workers
function eachWorker(callback) {
for (const id in cluster.workers) {
callback(cluster.workers[id]);
}
}
eachWorker((worker) => {
for (const worker of Object.values(cluster.workers)) {
worker.send('big announcement to all workers');
});
}
```
