how to poll efficiently in javascript

const poll = async function (fn, fnCondition, ms) {
  let result = await fn();
  while (fnCondition(result)) {
    await wait(ms);
    result = await fn();
  }
  return result;
};

const wait = function (ms = 1000) {
  return new Promise(resolve => {
    setTimeout(resolve, ms);
  });
};

let fetchReport = () => axios.get(reportUrl);
let validate = result => !result.data.summary;
let response = await poll(fetchReport, validate, 3000);
