How to sequentially execute functions in React?

I am trying to upload images to firebase storage and then when uploads finish, execute a try/catch block of codes with addDoc() command to create a doc inside fb database. The sample coding is as follows:

const abc = () => {

  array.map(() => {
    return uploadFilesToFb()
  })
  
  // then, when the above function finishes
  createDocInFb()
}

I heard about Promises, but is there any other way of doing this? I mean, in firebase there are .then functions but since I have a mapping I couldn't put addDoc() after .then of uploadFilesToFb(). If only alternative is promises, how can I achieve that with promises?
