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

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

When you encounter a Javascript error, it’s likely that your browser isn’t able to process the Javascript code. Most of the time, this is because of an outdated version of the software or browser.

Why I’m I experiencing the Windows 11 Javascript error?

The Windows 11 Javascript error may occur because of some of the reasons listed below:

  • Javascript is not enabled – When the error occurs, it means that your browser is not allowing the particular website to run JavaScript. Web browsers allow you to access and enable or disable JavaScript through the browser settings. If you are having problems using JavaScript on certain websites, this might help identify your issue.

  • Using an outdated browser – Occasionally, you may run into a JavaScript error in your web browser. This can happen when your browser is out of date. You’ll want to make sure that you’re using the latest version of your web browser.

  • Antivirus is blocking Javascript – Antivirus software such as your Firewall can block Javascript for security reasons. Certain antivirus programs may cause it to crash while browsing the Internet since they block the execution of JavaScript code 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 effective JavaScript code. Disable any browser extensions and add-ons, then run the site again to see if you have resolved the issue.

  • Browser cache – Sometimes an outdated browser cache can also lead to problems with JavaScript code in certain web browsers. Make sure you clear your browser’s cache and cookies before restarting it to resolve this issue.

  • Corrupted files – If your operating system files are corrupted, it can also cause problems with loading pages that rely on effective JavaScript code. Run SFC scan to replace corrupted system files with new ones and check if that fixes your problem.

If you suspect any of these could be the root cause of the Javascript error, proceed to try our solutions below.

Are there benefits of using Javascript?

If you’re not using JavaScript, you should be. Here are some advantages of Javascript:

  • Interoperability – JavaScript runs in all major browsers, so no matter what browser your users are running on their computers, smartphones, or tablets – whether it’s Internet Explorer, Chrome, Safari, Firefox, or Opera – your JavaScript code will run for every one of them.
  • Versatility – One of the great things about JavaScript is how versatile it is. It can be used in a huge variety of situations, both for server-side or client-side programming. It’s hard to overstate how much this versatility has contributed to its popularity.
  • Powerful – It’s easy to learn and use, flexible enough to allow for functional or object-oriented programming styles, and powerful enough to handle complex tasks.

Do I need JavaScript on my computer?

Yes, you do need JavaScript enabled in your web browser to view the majority of websites. Most websites use JavaScript for essential functionality such as menus, interactive maps, video players, and other dynamic elements.

If you have JavaScript disabled in your web browser, you will be unable to get the full experience of many websites. You’ll see a warning message if you have not enabled Javascript or if it’s not supported.

When it comes to security risks, disabling JavaScript will not protect you from all possible threats. That doesn’t mean that JavaScript can’t be used maliciously, though. 

Malicious JavaScript can be used to hijack cookies and other sensitive data, or even to change the appearance of a Web page so that users unwittingly download malware or reveal personal information (such as bank details).

As a safety precaution, it is always advisable to rely on secure and high-performance browsers for all your online activities.

In addition, you may experience issues with your browser as sometimes Javascript is not supported but worry not as we have an expert guide on how to fix it.
