| One way to do code-splitting is with `React.lazy`. However, this means that the code is not fetched until the component renders, which can cause network waterfalls. A more optimal solution is to use a router feature that fetches the code in parallel while the code is downloading. For example, React Router provides a `lazy` option to specify that a route should be code split and optimize when it is loaded: | ||
| コード分割を行う方法のひとつは、`React.lazy` を使用することです。しかし、この方法ではレンダーされる段階になって初めてコードが取得されるため、ネットワークウォーターフォールが発生する可能性があります。より良い解決策は、コードがダウンロードされる間に並行してコードをフェッチするためのルータ機能を使用することです。例えば、React Router は `lazy` オプションを提供しており、これを使ってルートをコード分割対象として指定し、読み込みタイミングを最適化できます。 |

ここよく分かっていません。とりあえず直訳していますが、「コードがダウンロードされる間に並行してコードをフェッチ」って何やねん、と思っています。
「コードがダウンロードされる間に並行してデータをフェッチ」と言いたい？ 「コードがダウンロードされる間に並行して別のルートのコードをを（プリ）フェッチ」と言いたい？ ただ直後のコードサンプルからはそのような雰囲気が全く感じられませんし…。
