This is useful for handling multiple asynchronous errors, where you want to catch all the errors and combine them to return just a single error.
Features
error instanceof Error === true
composable: error([error([err1, err2]), err3])
stack and message are combined in a nice way
array-like object, so you can access the original errors by looping over the error
If you just have one error, it looks exactly like raw error meaning, error(err).message === err.message && error(err).stack === err.stack
should work in the browser, though I haven't tested it yet
Installation
npm install combine-errors
