The Windows 11 Javascript error is common, especially if you use your browser a lot.

Javascript is a programming language that can be included in web pages to make them more interactive. When a user visits a webpage that contains JavaScript, the web browser executes (or executes) the script.

This means that websites can include programs that run directly in the browser itself, rather than requiring the user to download and install an application on their computer.

When you encounter a JavaScript error, it is likely that your browser is unable to process the JavaScript code. Most of the time, this is due to an outdated software or browser version.

Why am I encountering the Windows 11 Javascript error?

Windows 11 Javascript error can occur due to some of the reasons listed below:

  • Javascript is not enabled – When the error occurs, it means that your browser does not allow the particular website to run JavaScript. Web browsers allow you to access and enable or disable JavaScript through browser settings. If you’re having trouble using JavaScript on certain websites, this may help you identify your problem.
  • Using an outdated browser – Sometimes you may encounter a JavaScript error in your web browser. This can happen when your browser is outdated. You should ensure that you are using the latest version of your web browser.
  • Antivirus blocks JavaScript – Antivirus software such as your firewall may block JavaScript for security reasons. Some anti-virus programs may cause it to crash while browsing the Internet because they block JavaScript code execution on specific sites. Try disabling the antivirus program and see if it works.
  • Browser extensions – Browser extensions and add-ons can cause problems when accessing websites with efficient JavaScript code. Disable all browser extensions and add-ons, then run the site again to see if you’ve fixed the problem.
  • Browser cache – Sometimes an outdated browser cache can also lead to problems with JavaScript code in some web browsers. Make sure to clear your browser’s cache and cookies before restarting it to fix this issue.
  • Corrupt files – If your operating system files are corrupted, it can also lead to page load issues relying on efficient JavaScript code. Run SFC scan to replace corrupted system files with new ones and check if that fixes your problem.

If you think any of these might be causing the Javascript error, try our solutions below.

Do I need JavaScript on my computer?

If JavaScript is disabled in your web browser, you will not be able to take full advantage of many websites. You will see a warning message if you do not have Javascript enabled or if it is not supported.
