• I have an array of uid =["doc name 1","doc name 2"....]
• I have some data in firestore > "collection Name" > docmunets (uid which I have in above array ) > some data
• want to extract all data of all documents which are in uid array ,
• I'm using this code.. but problem is for loop dont wait for data to be fetched and then go to next iteration.
• how do I wait for every iteration to be completed. (await / async)
• here PostData.requests is an array which mentioned as uid
• here db is firebase firestore database ref

 useEffect(() => {
       if(PostData.requests==[]){
           setPageLoaded(true)
           
       }
       else{
            
        PostData.requests.forEach((element) => {
            db.collection("userPersonalData").doc(element).get().then((data)=>{
               let EachD = {key:element,Name:data.Name,url:profileDp}
               setFlatListData(EachD,...FlatListData)
           }).catch((e)=>{
               console.log(e);
           })
           setPageLoaded(true)
       });
           
       }
