Web Worker for Heavy Computation

// worker.ts
self.onmessage = (e) => {
  const { data } = e;
  const result = data.reduce((acc: number, n: number) => acc + n, 0);
  self.postMessage({ result });
};

// main.tsx
const worker = new Worker(new URL("./worker.ts", import.meta.url), { type: "module" });

worker.onmessage = (e) => console.log("Sum:", e.data.result);
worker.postMessage(Array.from({ length: 1e6 }, (_, i) => i));
