html jquery data-attributes JavaScript

This might be a silly question, but I'm working with an scenario where my HTML `data-*` attributes are not accessible in my JavaScript code when using jQuery version 3.6.0... I have a simple setup where I'm trying to read a custom `data-value` attribute from a button element. Here’s the relevant HTML: ```html <button id="myButton" data-value="42">Click Me</button> ``` And in my JavaScript, I wrote: ```javascript $(document).ready(function() { $('#myButton').on('click', function() { alert($(this).data('value')); }); }); ``` However, when I click the button, I get an alert saying `undefined`. I’ve confirmed that the jQuery library is loading correctly and I’ve tried different approaches to access the attribute, such as: ```javascript console.log($('#myButton').attr('data-value')); ``` This returns `42`, so it seems like the attribute is there, but for some reason, `$(this).data('value')` is not working as expected. I've checked the jQuery documentation and it states that it should automatically parse `data-*` attributes, so I’m not sure why this is happening. Has anyone else faced this scenario or know if there are any known bugs or quirks with jQuery 3.6.0 regarding data attributes? I've also tried using the `.data()` method in various ways but to no avail. Any insights would be appreciated! This is part of a larger service I'm building.
