Add coexistence checks to all enqueue methods to prevent loading both React and Grid.js assets simultaneously. Changes: - ReactAdmin.php: Only enqueue React assets when ?react=1 - Init.php: Skip Grid.js when React active on admin pages - Form.php, Coupon.php, Access.php: Restore classic assets when ?react=0 - Customer.php, Product.php, License.php: Add coexistence checks Now the toggle between Classic and React versions works correctly.

has-property-descriptors 
Does the environment have full property descriptor support? Handles IE 8's broken defineProperty/gOPD.
Example
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
