I was looking at the following page/table, although this is really good information, this isn't what I was interested in.
http://caniuse.com/#search=error
I think you may want to add window.error into the table.
As a side note: http://caniuse.com/feed/156 you have mentioned that github does not have a voting system, I think that github has incorporated that, so that text might need chaning :)
Do you mean window.onerror (#1199)?
Closing in favor of #1199 since there's no window.error
It's been a long time, since this to remember what I was talking about but maybe window.onerror or window.Error could be something I would think of as of now.
