❗️Что будет на выходе:

function* createCounter() {
  let count = 0;
  while (true) {
    const reset = yield ++count;
    if (reset) {
      count = 0;
    }
  }
}

const counter = createCounter();
console.log(counter.next().value);
console.log(counter.next().value);
console.log(counter.next(true).value);
console.log(counter.next().value);
