until now errors were always string. this commit changes this to error Objects, with the intention to be able to programmatically handle errors better (without string parsing). Example Use Case: Crawling a website and checking if links are valid. Current State: when a link points to a ressource which is not available, it returns an error with a string containing 404. State with this commit, it returns an error with an errorType, statusCode etc, which can be processed easily.

Error codes work well for HTTP errors, but the error system should be consistent. I agree with implementing a better error system, but non-HTTP errors should use the same system. This means that errors like failed logins and no results for selectors should also throw an error object with an error code. Also, try not to use Object.assign so the code works on ES5 platforms too. |
