SuppressedError: suppressed

The suppressed data property of a {{jsxref("SuppressedError")}} instance contains a reference to the original error that got suppressed because a new error was generated while handling it.

Value#

Any value. Like {{jsxref("Error/cause", "cause")}}, you cannot assume it's an {{jsxref("Error")}} instance, although it usually is the case.

{{js_property_attributes(1, 0, 1)}}
