Javascript – how to change promise.all to promise

I have two api calls in promise ,so i have used promise.all and it is working fine.

Now i have one api call is enough to get the results but still i am using promise.all it is working fine.

I try to use promise instead of promise.all(here i used one api call )

my code here :

Promise.all([getCall()])
          .then(res => {
            if (res[0].errorObject) {
              props.Error(res[0]);
            } else { 
              <!----code here--->
            }
          })
          .catch(err => {
            console.log(err); 
          });

    getCall()
  .then(res => {
    if (res.errorObject) {
      props.Error(res);
    } else { 
      // <!----code here--->
    }
  })

    You can using fetch()
    like this for example :

    useEffect(() => {
    fetch(url)
      .then((r) => r.json())
      .then((r) => {
        // save data from fetch request to state
        setData(r);
      });
  },[url]);
