@ -410,9 +410,10 @@ window.onbeforeunload = (e) => {
// a non-void value will silently cancel the close.
// It is recommended to use the dialog API to let the user confirm closing the
// application.
e.returnValue = false
e.returnValue = false // equivalent to `return false` but not recommended
}
```
_**Note**: There is a subtle difference between the behaviors of `window.onbeforeunload = handler` and `window.addEventListener('beforeunload', handler)`. It is recommended to always set the `event.returnValue` explicitly, instead of just returning a value, as the former works more consistently within Electron._
