I'm not following, why can't I use:

or:
e instanceof MyError
why does toString() have anything to do with this?
- pags 10y agoThis is what I do when working with my own Error types.
- prodigal_erik 10y agoIt's very likely someone did const e = new Error('bad stuff happened') e.name = 'MyError' without actually creating a MyError class to check with instanceof.
- Illniyar 10y agoUnless it's common in popular libraries/packages, I don't see why I need to take it into account. Which popular libraries do this? If it's just in a few places, it should be handled specifically, and use sane choices in other places.
