error.name missing regularly, contained in message

[thomasbachem]

I observed that while error.name is empty regularly, some browsers prepend it to the message.

E.g. when having

throw new DOMException("INDEX_SIZE_ERR");

Those are the observed values:

Opera 12.12 Name: null Message: Uncaught exception: Error: DOMException: INDEX_SIZE_ERR

Android Browser 4.2 + 4.4 Name: null Message: Uncaught DOMException: INDEX_SIZE_ERR

Edge 12 + 13 Name: null Message: DOMException: INDEX_SIZE_ERR

Or when having this:

throw new Error('Foo')

I saw this in the logs:

Safari 9 Name: null Message: Error: Foo

I also observed native errors like this:

Safari 9 Name: null Message: TypeError: foo.bar is not a function

Is there any interest in normalizing this stuff in TraceKit? I think we could parse the names out of the message quite easily using some RegEx magic.

I could implement this if it is something you would include in TraceKit.

My only concern is how do we insure it's always populated correctly. I'd be more than happy to accept this if you have tests for every browser and it works as expected. This would be a very welcoming change.

@thomasbachem would you mind submitting a pull request for this with tests.

@thomasbachem Any chance you can provide a pr for this :).

Sadly not :/ I'm out of coding for some time and focussing on other stuff.
