Forgotten request for componentDidCatch

An issue was brought up in https://github.com/facebook/react/issues/10461

which highlighted an opportunity for expansion on componentDidCatch(error, info) - being that info only returns one item prop: componentStack; there were a lot of good ideas to break this down into a detailed object of the error with an array for the stack trace.

This issue was then closed for https://github.com/facebook/react/issues/10922 - which told everyone the issue had moved to a new respository - but the referenced issue missed the very initial reason for the request. We didn't just want documentation, we wanted to look at a fuller featured object for error info.

So it was moved and closed again in https://github.com/reactjs/reactjs.org/issues/17

--- Opening this because the original issue from October has been lost:

Beginnen Sie mit der Prüfung der verknüpften Issues 10461, 10922 und des reactjs.org-Issues 17, um die ursprüngliche Anfrage und ihre Diskussion zu rekonstruieren. Das Issue nennt keine Dateien, Tests, keinen Einstiegspunkt für die Implementierung und keine Kriterien für den Abschluss; das gewünschte error-info-Objekt und das geeignete Repository müssten zunächst festgelegt werden.
