prr Build Status

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):

prr(obj, 'foo', 'bar')

Adjust the default options:

prr(obj, 'foo', 'bar', { enumerable: true, writable: true })

Do the same operation for multiple properties:

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':

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(...).
