DOMException: code property

Deprecated

Avoid using this feature in new projects. This feature may be a candidate for removal from web standards or browsers.

Note: This feature is available in Web Workers.

The code read-only property of the DOMException interface returns one of the legacy error code constants, or 0 if none match.

This field is used for historical reasons. New DOM exceptions don't use this anymore: they put this info in the DOMException.name attribute.
