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.

hasown 
A robust, ES3 compatible, "has own property" predicate.
Example
const assert = require('assert');
const hasOwn = require('hasown');
assert.equal(hasOwn({}, 'toString'), false);
assert.equal(hasOwn([], 'length'), true);
assert.equal(hasOwn({ a: 42 }, 'a'), true);
Tests
Simply clone the repo, npm install, and run npm test
