Why node.js Error objects sucks?..
| ~ $ node | |
| > const err = new Error('TEST') | |
| undefined | |
| > JSON.stringify(err) | |
| '{}' | |
| > Object.keys(err) | |
| [] | |
| > Reflect.ownKeys(err) //where is a 'name'? | |
| [ 'stack', 'message' ] | |
| > for(let k in err) console.log(k) | |
| undefined | |
| > err.field = 'bla' | |
| 'bla' | |
| > console.log(err) //do you see this 'bla' at the end?... | |
