| # 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(...)`. |
