Maybe this will work.

const array=["id1","id2",...]//array of ids 
async function fetchData(){
  array.map(id=>{
    await fetch(<call to database using the id).then(res=>{//OK})
      .catch(err=> {not ok})
  })
}

Async await are a cleaner way to work with asynchronous functions like this.

You can use async/await in loop as below. 

const array=["id1","id2",...]


fetchData = () => {
  array.forEach(async (id) => {
    try {
      await res = fetch(id)
      // Do something with your res 
    } catch (err) {
      console.log(err)
    }
  })
}
