I keep running into I'm relatively new to this, so bear with me... I'm working with an scenario where I'm trying to dynamically add a `<script>` tag to my HTML using jQuery's `.append()` method, but it doesn't seem to execute as expected. Here's a simplified version of my code: ```javascript $(document).ready(function() { $('#addScript').on('click', function() { var scriptContent = 'console.log("Script executed!");'; var scriptTag = '<script>' + scriptContent + '<\/script>'; $('#scriptContainer').append(scriptTag); }); }); ``` When I click the button with id `addScript`, the script tag gets appended to the `#scriptContainer`, but I don't see the expected output in the console. In fact, it seems like the script won't execute at all. I've tried various techniques, including using jQuery's `.getScript()` method, but with no success. Additionally, I'm aware that directly injecting script tags can sometimes lead to security issues, so I am sanitizing the input. However, even when I try to append a script tag without dynamic content, it still doesn't execute. I tried adding a small delay using `setTimeout()` to ensure that the page is fully loaded before executing, but that didn't help either. I'm currently using jQuery version 3.6.0, and my browser is Chrome 93. Any help regarding why the appended script does not execute would be greatly appreciated! For context: I'm using Javascript on macOS. Thanks for your help in advance!
