Target objects defaultView
Interface PromiseRejectionEvent

Examples

window.addEventListener("unhandledrejection", function (event) {
  console.warn("WARNING: Unhandled promise rejection. Shame on you! Reason: "
               + event.reason);
});

Inheritance

The unhandledrejection event implements the PromiseRejectionEvent interface, which inherits from Event. You can use the properties and methods defined on these interfaces.
