Unable to retrieve Firebase downloadURL from .getDownloadURL() promise

I am trying to retrieve the downloadURL from an image I uploaded to Firebase. No problem getting the correct URL inside the promise.

I don't understand why downloadURL is still undefined after I set it equal to the url returned in the .then statement.

let downloadURL;

    firebase
      .storage()
      .ref()
      .child('project_images/' + imageName)
      .getDownloadURL()
      .then(url => {
        downloadURL = url;
        console.log(downloadURL); //logs the correct downloadURL needed
      })
      .catch(error => {});

    console.log(downloadURL); //still undefined

I feel like I am missing something stupid but for the life of me I can't see what it is. Any help appreciated. Thank you!

Does it log the undefined before the one inside the promise?

It's likely just not completing the promise before you try and log outside the function calls.
