async await with setInterval

Question

function first(){
  console.log(\'first\')
}
function second(){
  console.log(\'second\')
}
let interval = async ()=>{
  await setInterval(first,2000)
  await set         


        

Answer 1

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)
