hashargs.js

hashargs is a simple decorator utility that allows any JavaScript function to be called with a hash of named arguments. Any argument that isn't named in the hash is still passed through as undefined as if it was set positionally.

Installation

npm install hashargs

Usage

> hashify = require('hashargs');
[Function]

'2': undefined,
'3': undefined }

> t({bar: 'hello world', blah: 1234})
{ '0': undefined, '1': 'hello world', '2': undefined, '3': 1234 }

{ '0': { bar: 'hello world' },
'1': undefined,
