Experimenting with Node `timers/promises`

timers.ts

import { setInterval } from "timers/promises";

const createCounter = (initial = 0) => {
  let value = initial;
  return () => ++value;
};

const start = Date.now();

for await (const incr of setInterval(1000, createCounter())) {
  const i = incr();

  console.log(i, Date.now() - start);

  if (i >= 10) {
    break;
  }
}

console.log("Done!");
