# prr [](http://travis-ci.org/rvagg/prr) An sensible alternative to `Object.defineProperty()`. Available in npm and Ender as **prr**. ## Usage Set the property `'foo'` (`obj.foo`) to have the value `'bar'` with default options (`'enumerable'`, `'configurable'` and `'writable'` are all `false`): ```js prr(obj, 'foo', 'bar') ``` Adjust the default options: ```js prr(obj, 'foo', 'bar', { enumerable: true, writable: true }) ``` Do the same operation for multiple properties: ```js prr(obj, { one: 'one', two: 'two' }) // or with options: prr(obj, { one: 'one', two: 'two' }, { enumerable: true, writable: true }) ``` ### Simplify! But obviously, having to write out the full options object makes it nearly as bad as the original `Object.defineProperty()` so we can simplify. As an alternative method we can use an options string where each character represents a option: `'e'=='enumerable'`, `'c'=='configurable'` and `'w'=='writable'`: ```js prr(obj, 'foo', 'bar', 'ew') // enumerable and writable but not configurable // muliple properties: prr(obj, { one: 'one', two: 'two' }, 'ewc') // configurable too ``` ## Where can I use it? Anywhere! For pre-ES5 environments *prr* will simply fall-back to an `object[property] = value` so you can get close to what you want. *prr* is Ender-compatible so you can include it in your Ender build and `$.prr(...)` or `var prr = require('prr'); prr(...)`. ## Licence prr is Copyright (c) 2013 Rod Vagg [@rvagg](https://twitter.com/rvagg) and licensed under the MIT licence.
