EnhancedError

Adds missing Error's feature in JS - ability to provide error code or other information;

Feels like natural Error when printing in console.

npm install --save enhancederror

commonjs:

import EnhancedError from 'enhancederror';

umd:

<srctipt src="https://npmcdn.com/enhancederror/lib/enhancederror.umd.js"></script>

const a = new EnhancedError('Message', 10085);

const b = new EnhancedError({
  message: 'OtherMessage',
  code: 10085,
  customProp: true
});

a.code === b.code; // true

b.otherProp; // true

a instanceof EnhancedError; // true
a instanceof Error; // true
