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.

|
||
|
||
An ESnext spec-compliant sync iterator helpers shim/polyfill/replacement that works as far down as ES3.
|
||
|
||
This package implements the [es-shim API](https://github.com/es-shims/api) “multi” interface. It works in an ES3-supported environment and complies with the [iterator helpers spec](https://tc39.es/proposal-iterator-helpers/) and the [iterator sequencing spec](https://tc39.es/proposal-iterator-sequencing/).
|
||
|
||
Because the `Iterator.prototype` methods depend on a receiver (the `this` value), the main export in each subdirectory takes the iterator to operate on as the first argument.
|
||
|
||
The main export of the package itself is simply an array of the available directory names. It’s sole intended use is for build tooling and testing.
|
||
|
||
## Supported things
|
||
|
||
- [`Iterator` constructor](https://tc39.es/proposal-iterator-helpers/#sec-iterator-constructor)
|
||
- [`Iterator.prototype`](https://tc39.es/proposal-iterator-helpers/#sec-iterator.prototype)
|
||
- [`Iterator.concat`](https://tc39.es/proposal-iterator-sequencing/)
|
||
- [`Iterator.from`](https://tc39.es/proposal-iterator-helpers/#sec-iterator.from)
|
||
- [`Iterator.zip`](https://tc39.es/proposal-joint-iteration/#sec-iterator.zip)
|
||
- [`Iterator.zipKeyed`](https://tc39.es/proposal-joint-iteration/#sec-iterator.zipkeyed)
|
||
- [`Iterator.prototype.constructor`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.constructor)
|
||
- [`Iterator.prototype.drop`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.drop)
|
||
- [`Iterator.prototype.every`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.every)
|
||
- [`Iterator.prototype.filter`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.filter)
|
||
- [`Iterator.prototype.find`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.find)
|
||
- [`Iterator.prototype.flatMap`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.flatmap)
|
||
- [`Iterator.prototype.forEach`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.foreach)
|
||
- [`Iterator.prototype.includes`](https://tc39.es/proposal-iterator-includes/)
|
||
- [`Iterator.prototype.map`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.map)
|
||
- [`Iterator.prototype.reduce`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.reduce)
|
||
- [`Iterator.prototype.some`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.some)
|
||
- [`Iterator.prototype.take`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.take)
|
||
- [`Iterator.prototype.toArray`](https://tc39.es/proposal-iterator-helpers/#sec-iteratorprototype.toarray)
|
||
|
||
## Environments where this is needed
|
||
|
||
- node < v22, Chrome < v122, Safari <= v17.1, Firefox <= v125: not implemented
|
||
- node v22, Chrome v122 - v130: has a [bug](https://issues.chromium.org/issues/336839115) where `{ next: null }` is not properly rejected
|
||
- node v22 - v24, Chrome v122 - v134: missing early-error `IteratorClose` when argument validation fails (e.g., non-callable mapper does not call the iterator's `return` method)
|
||
- all environments lack Iterator.concat, Iterator.zip, Iterator.zipKeyed, Iterator.prototype.includes
|
||
|
||
## Getting started
|
||
|
||
```sh
|
||
npm install --save es-iterator-helpers
|
||
```
|
||
|
||
## Usage/Examples
|
||
|
||
Using explicit imports:
|
||
|
||
```js
|
||
const map = require('es-iterator-helpers/Iterator.prototype.map');
|
||
const toArray = require('es-iterator-helpers/Iterator.prototype.toArray');
|
||
const assert = require('assert');
|
||
|
||
const iterator = [1, 2, 3].values();
|
||
|
||
const mapped = map(iterator, (x) => x + 10);
|
||
assert.deepEqual(
|
||
mapped.next(),
|
||
{
|
||
done: false,
|
||
value: 11,
|
||
}
|
||
);
|
||
assert.deepEqual(
|
||
toArray(mapped),
|
||
[12, 13]
|
||
);
|
||
```
|
||
|
||
Shim using `require`:
|
||
|
||
```js
|
||
require('es-iterator-helpers/auto'); // shim all of the methods
|
||
|
||
require('es-iterator-helpers/Iterator.prototype.map/auto'); // shim the “map” method
|
||
```
|
||
|
||
Shim using `import` syntax:
|
||
|
||
[](#preventEval)
|
||
```js
|
||
import 'es-iterator-helpers/auto'; // shim all of the methods
|
||
|
||
import 'es-iterator-helpers/Iterator.prototype.map/auto'; // shim the “map” method
|
||
```
|
||
|
||
## Tests
|
||
Simply clone the repo, `npm install`, and run `npm test`
