Problem with async and fetch in JavaScript

Question

My problem is that I would like to return the value of a variable gotten from fetch outside of the fetch function. This is my current code:

const fetch = require('node-fetch');
var playerName = "kada49";

async function fetchUUID() {
    const response = await fetch(`https://api.mojang.com/users/profiles/minecraft/${playerName}`);
    const data = await response.json();
    return data;
}

fetchUUID()
    .then(data => {
    let playerUUID = data.id;
    return playerUUID;
  });

var playerUUID = fetchUUID();
console.log(playerUUID);

as a response I get this in the console:

Promise { <pending> }

WHat am I doing wrong?
