Unfortunately, you cannot use Laravel helper functions directly in JavaScript as Laravel is a PHP framework and JavaScript is a different programming language. However, here are some possible ways to use Laravel helper functions with parameters in JavaScript:

1. Create a separate endpoint in your Laravel application that returns the result of the desired helper function with the provided parameters. Then, use an AJAX request from your JavaScript to call this endpoint and retrieve the response.

Example:

In your Laravel controller:

public function myHelperFunction($param1, $param2) {
    return myHelperFunction($param1, $param2);
}

In your JavaScript:

$.ajax({
    url: '/helper/myHelperFunction',
    data: { param1: 'value1', param2: 'value2' },
    success: function(response) {
        // use the response
    }
});

1. Add the result of the helper function to your view's JavaScript object, and then access that object in your JavaScript code.

Example:

In your server-side view:

<script>
    var myHelperResult = "{{ myHelperFunction($param1, $param2) }}";
</script>

In your JavaScript:

// use the "myHelperResult" variable

Note that this approach may not work if your helper function returns complex data types (such as arrays or objects) that cannot be easily represented as a string.

1. Use a JavaScript library that implements the same functionality as the Laravel helper function. For example, the Moment.js library provides similar date and time formatting features to the Carbon PHP library that is included with Laravel.

Example:

In your JavaScript using Moment.js:

var now = moment();
var formattedDate = now.format('YYYY-MM-DD');

In your PHP using Carbon:

use Carbon\Carbon;

$now = Carbon::now();
$formattedDate = $now->format('Y-m-d');
