Does the environment have full property descriptor support? Handles IE 8's broken defineProperty/gOPD.
|
|
|
|
## Example
|
|
|
|
```js
|
|
var hasPropertyDescriptors = require('has-property-descriptors');
|
|
var assert = require('assert');
|
|
|
|
assert.equal(hasPropertyDescriptors(), true); // will be `false` in IE 6-8, and ES5 engines
|
|
|
|
// Arrays can not have their length `[[Defined]]` in some engines
|
|
assert.equal(hasPropertyDescriptors.hasArrayLengthDefineBug(), false); // will be `true` in Firefox 4-22, and node v0.6
|
|
```
|
|
|
|
## Tests
|
|
Simply clone the repo, `npm install`, and run `npm test`
