固定長のPromise.allのコールバック関数の引数は分割代入で受けるといい感じ

Promise.allのコードのサンプルを見ると、大体

Promise.all([hoge(),fuga()]).then(results => {
  results[0]//hogeの結果
  results[1]//fugaの結果
});

という感じになっていますが、Promise.allの引数の配列の長さが決まっている場合

Promise.all([hoge(),fuga()]).then(([hoge,fuga]) => {
  hoge//hogeの結果
  fuga//fugaの結果
});

と書くと可読性が高くていい感じです。
async/awaitを使う場合でも

const [hoge,fuga] = await Promise.all([hoge(),fuga()]);

こんな具合でOK。
