| Define a data property on an object. Will fall back to assignment in an engine without descriptors. | |
| The three `non*` argument can also be passed `null`, which will use the existing state if available. | |
| The `loose` argument will mean that if you attempt to set a non-normal data property, in an environment without descriptor support, it will fall back to normal assignment. | |
| ## Usage | |
| ```javascript | |
| var defineDataProperty = require('define-data-property'); | |
| var assert = require('assert'); | |
| var obj = {}; | |
| defineDataProperty(obj, 'key', 'value'); | |
| defineDataProperty( | |
| obj, | |
| 'key2', | |
| 'value', | |
| true, // nonEnumerable, optional | |
| false, // nonWritable, optional | |
| true, // nonConfigurable, optional | |
| false // loose, optional | |
| ); | |
| assert.deepEqual( | |
| Object.getOwnPropertyDescriptors(obj), | |
| { | |
| key: { | |
| configurable: true, | |
| enumerable: true, | |
| value: 'value', | |
| writable: true, | |
| }, | |
| key2: { | |
| configurable: false, | |
| enumerable: false, | |
| value: 'value', | |
| writable: true, | |
| }, | |
| } | |
| ); | |
