What is a JavaScript Error?

All websites on the Internet are built using scripting languages. Almost all websites incorporate HTML, which is often partnered with the scripting language JavaScript. JavaScript was the original way to introduce dynamics into web pages. The heart of many popular web applications use JavaScript. Unlike other Internet scripting languages, the coding is executed right there on your computer rather than on the server side.

Problems Related to JavaScript Errors

JavaScript errors can be aggravating if you are browsing the Internet. The errors affect many websites' functionality. It is even more aggravating when the pop ups are continuous.

What problems can JavaScript Errors Cause?

  • Many websites rely on advertising income. The adverts displayed on these websites are written in JavaScript. If you have problems with the Java applet within your registry, you may lose functionality when visiting some websites.
  • Many times your browser can completely crash if it is on a JavaScript-heavy website, causing a number of errors. It may not even display an error message. If you notice your browser hanging on certain websites, this could be a JavaScript error.
  • Since JavaScript is executed clientside, many people have written code which will affect your computer in various ways. This isn’t instantly detectable by the user until problems start occurring.
  • Repeated JavaScript errors can leave information on your computer which lead to future system crashes and file errors.

A particular hint that may indicate that your computer is having problems is if you visit a well-known website that has JavaScript installed, and you experience errors. Generally, you wouldn’t expect to see errors in big-name websites. If you are persistently given errors, it may be time for a registry clean up.

How to Fix JavaScript Errors

You may see two types of errors while browsing a website:

  1. A syntax error which is normally the result of faulty coding. These errors cannot be solved on your own. So we suggest getting in touch with the webmaster to report the problem.
  2. Runtime errorsusually boil down to problems within Window's registry.

If you are greeted with these errors, try pressing F5 to see if the page reloads. If not, you will need to check if JavaScript is turned on in your Internet browser. This is the process for Internet Explorer. The options should be similar for any other Internet browser.

  1. Click Tools; Internet Options
  2. Click the Security Tab
  3. Select the option called "Custom Level"
  4. Scroll down to the "JavaScript" option and check if it is turned on.

The second option is an update of your Internet browser. To do this, head on over to the developer's website and download their updated software. Once downloaded, the process is self-explanatory.

If the problem still occurs, it may require some deeper digging. Persistent runtime errors usually mean problems in the Windows registry, particularly if the errors are not limited to one website.

You may be tempted to repair the Windows registry by yourself; however, we do not suggest this even if you are an experienced computer user. There are two problems with doing this manually. The first is that you could cause irreparable damage to your computer if you do something even slightly wrong. The second is that you don't actually know what is causing your errors and therefore don't have any idea where to start.
