Classes

GrigsonParseErrorEvent

Constructor

new GrigsonParseErrorEvent(error: unknown): GrigsonParseErrorEvent

Methods

composedPath(): EventTarget[]

The **`composedPath()`** method of the Event interface returns the event's path which is an array of the objects on which listeners will be invoked. [MDN Reference](https://developer.mozilla.org/docs/Web/API/Event/composedPath)
