reason property

JSAny? get reason

The reason read-only property returns a JavaScript value that indicates the abort reason.

The property is undefined when the signal has not been aborted. It can be set to a specific value when the signal is aborted, using AbortController.abort or AbortSignal.abort_static. If not explicitly set in those methods, it defaults to "AbortError" DOMException.

Implementation

external JSAny? get reason;
