Module parse failed: Unexpected token

在 cordova 編譯時突然出現錯誤訊息

Module parse failed: Unexpected token.

You may need an additional loader to handle the result of these loaders.

錯誤的地方是之前明明可以過的語法，比如

>  this.loading?.reset();
>  const path = route ? The${route}Container : "TheShell";
>  const route = searchParams.get("route") ?? undefined;

原因是這樣，所以要在 package.json裡面的 browserslist 部分修改

"browserslist": [
    "> 1%",
    "last 2 versions",
    "not dead"
    "IE 11"    < 加這個
  ],
