async await with setInterval

by

As mentioned above setInterval does not play well with promises if you do not stop it. In case you clear the interval you can use it like:

async function waitUntil(condition) {
  return await new Promise(resolve => {
    const interval = setInterval(() => {
      if (condition) {
        resolve('foo');
        clearInterval(interval);
      };
    }, 1000);
  });
}

Later you can use it like

const bar = waitUntil(someConditionHere)
